Cannot pass variables to Django 3 method from HTML template - python-3.x

I am a Django newbie who is trying to convert an existing HTML based website to Django 3. The only complex piece of this page is a call to a Django method that uses the django.core.mail package and everything works, but, I am trying to pull some data off of the HTML template and pass it to this method.
The method works, only it sends a blank email. I am trying to pass contact information that the end user would fill out on the form. If I hard code the data into the method it works.
I have tried passing the data through urls.py, but, everything I try fails to even parse when I call the method. When I use a request.GET.get everything seems to work, just no data.
I was hoping to use something similar to JQuery like the following in the method.
name = str(request.GET.get('Name:', '').strip())
email = str(request.GET.get('Email:', '').strip())
msg1 = str(request.GET.get('Message:', '').strip())
with the fields being in the HTML form.
I am going to include some of the relevant configuration items below.
urls.py
from django.urls import path
from django.conf import settings
from django.conf.urls import url
from django.conf.urls.static import static
from . import views
app_name = 'willdoit'
urlpatterns = [
path('', views.index),
#url(r'^contact/(?P<name>\.+)/(?P<email>\.+)/(?P<msg1>\.+)/?$', views.contact, name='contact'),
path('contact/', views.contact, name='contact'),
]
views.py
def contact(request):
name1 = request.GET.get('name', '')
email1= request.GET.get('email', '')
msg1 = request.GET.get('message1', '')
subject = 'Work needed'
from_email = settings.DEFAULT_FROM_EMAIL
message = name + ' ' + email + ' ' + msg1
recipient_list = ['pkustra914#gmail.com']
send_mail(subject, message, from_email, recipient_list, fail_silently=False)
return HttpResponse('Success')
Relevant HTML Template section
<div class="contact_content">
<div class="col-md-6 col-sm-6 col-xs-12">
<div class="contact_message wow fadeInLeft" data-wow-duration="1.5s">
<form action="#" id="formid">
<form action="#" id="formid">
<div class="form-group"> <input class="form-control" name="name"
placeholder="Name" required="" type="text"> </div>
<div class="form-group"> <input class="form-control" name="email"
placeholder="Email" required="" type="email"> </div>
<div class="form-group">
<div class="Descrizione"> <label for="InserisciDescrizione"
class=""><b>Message</b></label> <textarea class="form-control"
id="message" placeholder="Type message:" name="message1" rows="6" cols="50"
title="Message"></textarea> </div>
<a id="submit" href="{% url 'willdoit:contact' %}" class="btn btn-primary">Submit</a>
I would prefer to use the request.GET.get method, but, there is a lot more documentation passing it through the urls.
Thanks.

Your code request.GET.get('Name:', '') returns empty string when the key 'Name:' is not found.
To fix this, use request.GET.get('name', '') request.GET.get('email', '') request.GET.get('message', '') instead.
Details
I see that you are using a with template tag for nothing. The following line of code does not change the name attribute string to PascalCase. See with template tag (Docs)
{% with Name=name Email=email Message=message %}
Even if it worked, your code should be calling request.GET.get('Name', '') instead of request.GET.get('Name:', ''). But it won't work, as with would not modify the attribute names in the GET request.
#EDIT1
There are apparently more bugs in your html code. I have reformatted your code and listed up some obvious bugs.
<!--REFORMATTED CODE-->
<form action="#" id="formid"> <--------------DUPLICATES, remove one
<form action="#" id="formid"> <--------------DUPLICATES, remove one
<div class="form-group"> <input class="form-control" name="name"
placeholder="Name" required="" type="text"> </div>
<div class="form-group"> <input class="form-control" name="email"
placeholder="Email" required="" type="email"> </div>
<div class="form-group">
<div class="Descrizione">
<label for="InserisciDescrizione" class=""><b>Message</b></label>
<textarea class="form-control" id="message"
placeholder="Type message:" name="message1" rows="6" cols="50"
title="Message"></textarea>
</div>
<a id="submit" href="{% url 'willdoit:contact' %}"
class="btn btn-primary">Submit</a>
<-------- MISSING DIV END TAG
<-------- MISSING FORM END TAG
Furthermore, you are calling the server by url directly using the following code:
<a id="submit" href="{% url 'willdoit:contact' %}" class="btn btn-primary">Submit</a>
This does not tell the page which form you want to submit (there are cases where there are multiple forms).
You have two choices:
Replace the tag with standard html form submit button <input type="submit">, and add the url to the action attribute of the form. Use the following code to do so:
<form action="{% url 'willdoit:contact' %} id="formid">
...
...
<input id="submit" type="submit" class="btn btn-primary" value="Submit"/>
</form>
This solution will by default use the GET method to send a request to the server, and you will be able to get the inputted values by calling request.GET.get(name).
If you are using JQuery, you can replace the with the following:
Submit
This is however not recommended. Please use the standard html form input tag for the submit button.

Great. Moving the method call to the form tag worked great.
Thanks! You guys are the best.

Modx Formit simple contact from

I try to create a simple contact form, but I didn't get any message, the post request is made. I am pretty new with Modx.
What I tried:
Link 1
Link 2
I created 2 Chunks (emailChunkTpl and MyEmailChunk), and in my template I call for the [[$MyEmailChunk]]. Obviously I did something wrong but I am not sure what. The code is like in the examples, but with some changes,like my email.
[[!FormIt?
&hooks=`email,FormItSaveForm `
&emailTpl=`emailChunkTpl`
&emailTo=`myEmail#gmail.com`
&emailUseFieldForSubject=`1`
]]
<form action="[[~[[*id]]]]" method="post" class="contactForm">
<div class="row input-section-child">
<div class="col input-contact">
<input value="[[!+fi.input-name]]"class="input-name" name="input-name" id="input-name" type="text" placeholder="your name" />
<input value="[[!+fi.input-email]]" class="input-email" name="input-email" id="input-email" type="text" placeholder="email address" />
</div>
<div class="col input-contact-text">
<input value="[[!+fi.input-textare]]"class="input-textare" name="input-textare" id="input-textare" type="textare" placeholder="message" />
</div>
</div>
<div class="row second-row">
<div class="col checkbox">
<input value="[[!+fi.input-checkbox]]" class="input-checkbox" name="input-checkbox" id="input-checkbox" type="checkbox" ><span class="input-checkbox-span">I agree to the Privacy policy.</span>
</div>
<div class="col">
<button type="submit" class="send-button">SEND</button>
</div>
</div>
<a href="#intro" class="back-to-top"><img src="images\arrow-back.svg" /><span>Back to top</span>
</div>
</from>
You should start with cleaning up your markup, it is not valid HTML. There is a typo in your closing form tag (/from), an extra closing div tag, there is no input type of textare as far as I know, and you are missing white space around some classes. You can validate HTML here: https://validator.w3.org/
You can test to make sure your site is setup properly to send an email. There is a snippet for this called QuickEmail, download it from the extras tab in the MODX manager.
Once you're sure your site can send email, then start with a stripped down version of the Formit call -- remove all hooks except email and get it working with that first. Then add hooks one at a time.

How to scrape product details which is inbetween <div> tag using Xpath

I am trying to get the word BIBA. I am getting output like \n,\n,\nBIBA,\n But I only want "BIBA".
Please help me to get that name using xpath.
Thank you.

I highly recommend to use Scrapy Item Loaders and Input and Output processors:
def strip_word(value):
value = value.strip()
return value
class MyItem(scrapy.Item):
my_word_field = scrapy.Field(
input_processor=TakeFirst(),
output_processor=MapCompose(strip_word)
)
How about this:
response.xpath('normalize-space(//div[#class="pdp-bname"])')

How to take value from ng-slider in ng component in Angular

I have created a slider as in input field. I am not able to get its value in formGroup. I am stucked.
My code:
<form [formGroup]="Form" novalidate (ngSubmit)="BasicDetail(Form.value)>
<div class="col-md-8">
<div class="drags">
<input class="ex6" type="text" data-slider-min="0" data-slider-max="10" data-slider-step="1" data-slider-value="5"/>
</div>
</div>
</form>
Help needed.
Make sure input is slider type, meaning range
type="range"
If you're going to create a submit form fucntion where you feed your form, then it's template-driven, so get rid of your formGroup property, (assuming this is what you want since you've shown no effort on the component.ts side)
Give your form a reference form
<form #form="ngForm" novalidate (ngSubmit)="BasicDetail(form.value)">
Create a button to submit
<button class="btn btn-primary"type="submit"> Submit </button>
Make sure to give your form input a name, and assign it ngModel
If you want also direct access, create a two-way binding, say with variable called rangeValue
[(ngModel)]="rangeValue"
Make sure you're actually using real range input types, I don't know where you got data-slider from
<form #form="ngForm" novalidate (ngSubmit)="BasicDetail(form.value)">
<div class="col-md-8">
<div class="drags">
<input class="ex6"
type="range"
min="0" max="10"
step="1"
name="someRange"
[(ngModel)]="rangeValue"
ngModel/>
</div>
</div>
<button class="btn btn-primary"type="submit"> Submit </button>
</form>
Inside your component.ts, declare variable and try to log it on submit
rangeValue = 5;
constructor( ) {}
ngOnInit() {
}
BasicDetail(form: any) {
console.log(this.rangeValue);
console.log(form.someRange);
}

How do i create a get query in nodeJS based on information contained in checkboxes

I am trying to build an app that lets users find other users with a specific combination of skills. I ask the users to select which skills they are looking for via checkboxes but I'm not sure how to request for the status of that checkbox in my function.
My function currently is:
UserInfo.find()
.where('skill1').equals('')
.where('skill2').equals('')
.where('skill3').equals('')
.limit(10)
.then(function(doc) {
res.render('index', {items: doc});
});
It works properly if I set the equals('') to true or false but I'm not sure how to set it dynamically. My HTML code for the checkboxes is:
<form action="/getskills" method="get">
<div class="input">
<label for="skill1">Skill1</label>
<input type="checkbox" id="skill1" name="skill1" value="skill1"/>
</div>
<div class="input">
<label for="skill2">Skill2</label>
<input type="checkbox" id="skill2" name="skill2" value="skill2"/>
</div>
<div class="input">
<label for="skill3">Skill3</label>
<input type="checkbox" id="skill3" name="skill3" value="skill3"/>
</div>
FIND SKILL
</form>
How can I create and integrate a function to check the value of the checkbox and set the value of the required skill to either true or false?
Thanks in advance for your help.
The problem is that you are using an <a> element to perform the request to the server instead of <input type="submit">. Without a submit button, the elements on your form will not be submitted with the request. Modify your html to this
<form action="/getskills" method="get">
<div class="input">
<label for="skill1">Skill1</label>
<input type="checkbox" id="skill1" name="skill1" value="skill1" />
</div>
<div class="input">
<label for="skill2">Skill2</label>
<input type="checkbox" id="skill2" name="skill2" value="skill2" />
</div>
<div class="input">
<label for="skill3">Skill3</label>
<input type="checkbox" id="skill3" name="skill3" value="skill3" />
</div>
<input type="submit" value="FIND SKILL" />
</form>
then in your Node.js code (I assume you are using express), you can get the checkbox values as query parameters as follows:
//I'm assuming the req parameter is passed in to the express get() method
UserInfo.find()
.where('skill1').equals(req.query.skill1)
.where('skill2').equals(req.query.skill2)
.where('skill3').equals(req.query.skill3)
.limit(10)
.then(function(doc) {
res.render('index', {items: doc});
});

passing get request from bootstrap button

How do I trigger a get request from a bootstrap button? I have the following code:
<form class="navbar-form navbar-right" role="form">
<div class="form-group">
<input type="text" placeholder="Email" class="form-control">
</div>
<div class="form-group">
<input type="password" placeholder="Password" class="form-control">
</div>
<button type="submit" class="btn btn-success">Sign in</button>
<button type="submit" class="btn btn-warning" value="/signup" id="submit">Sign up</button>
</form>
and would like this button to perform a get request with the following value "signup"
I am using a MEAN stack and the routes are set up so when the app is accessed with the get value /signup it goes to the signup page. But I am not able to get the bootstrap 3 button to post a get a request.
On your form you will need the following two attributes:
Action = "{URL TO SEND THE FORM TO}"
Method = "{GET or POST}"
For a signup with a username and password you should really think about doing a POST request so the form element should look like (for a POST request):
<form action="/signup" method="POST" class="navbar-form navbar-right" role="form">
or for a get request:
<form action="/signup" method="GET" class="navbar-form navbar-right" role="form">
