I'm using Chameleon in the Pyramids Framework and want to repeat nested list while rendering the template.
My minimized HTML-Code is:
1. <ul>
2. <li tal:repeat="item items">
3. <input tal:attributes="id item.id; onclick item.url">
4. <label tal:repeat="premise item.values" tal:attributes="for item.id; id premise.id">
5. <label tal:replace="premise.title"/>
6. </label>
7. <label tal:attributes="for item.id" tal:content="item.title"/>
8. </li>
9. </ul>
Whereby I got the following json-Data
[{
'url': 'location.href="http://..."',
'values':
[{
'id': '70',
'title': 'some title 1'
}],
'attitude': 'justify',
'id': '68',
'title': 'some title 2'
}, {
'url': 'null',
'values':
[{
'id': '0',
'title': 'some title 3!
}],
'attitude': 'justify',
'id': '0',
'title':
'some title 4'
}]
If I kill HTML-lines 4.-6., everything is fine, otherwise Pyramid/Chameleon throws:
File "/usr/local/lib/python3.4/dist-packages/chameleon/tal.py", line 471, in __call__
iterable = list(iterable) if iterable is not None else ()
TypeError: 'builtin_function_or_method' object is not iterable
Anyone some idea?
Thanks to #pyramid in the IRC i got the first hint, which is mentioned in the comment. But..never ever name a key 'value' or 'values'!

I have created a vue.js router and inserting the links found in an array using the structure found hereafter. This displays the links horizontally. However, I would like to insert dropdowns, instead of simple links. Can this be done using this or similar structure somehow?
<nav style="text-align: right">
<router-link class="spacing" v-for="routes in links"
v-bind:key="routes.id"
:to="`${routes.page}`">{{routes.text}}</router-link>
</nav>
links: [
{
id: 0,
text: 'Buy',
page: '/Buy'
},
{
id: 1,
text: 'Sale',
page: '/Sale'
},
{
id: 2,
text: 'Transactions',
page: '/Transactions'
},
{
id: 3,
text: 'Help',
page: '/Help'
}
]
Yeah, there are a few ways you could do that, though you'll have to loop over something different than the <router-link>, since that component renders an <a> tag.
I would first adjust your HTML to allow for the drop-down interaction you want, whether it's hover- or click-based, then change your data structure and loop to support it.
I might do something like this:
<nav style="text-align: right">
<div
class="nav-item"
v-for="link in links" // Move loop to container of shown link and it's dropdown markup
>
<router-link
:key="link.id"
:to="`${link.page}`"
>
{{ link.text }}
</router-link>
<div class="nav-item-drawer">
<router-link
v-for="subLink in link.subLinks"
:key="subLink.id"
:to="`${subLink.page}`"
>
{{ subLink.text }}
</router-link>
</div>
</div>
</nav>
with the following data structure:
links: [
{
id: 0,
text: 'Buy',
page: '/Buy',
subLinks: [
{
id: 0,
text: 'Buy Sublink 1',
page: '/Buy-more'
},
{
id: 1,
text: 'Buy Sublink 2',
page: '/Buy-less'
},
]
},
{
id: 1,
text: 'Sale',
page: '/Sale'
},
//...
]
I want something like this-
<input type="text" id="agentsignupname" name="agentsignupname"
class="form-control" value={{typeof name!="undefined"?name:" "}}>
This peice of code is not working as it shows-
Parse error on line 14:
...rol" value={{typeof name!="undefined"?na
-----------------------^
Expecting 'CLOSE_RAW_BLOCK', 'CLOSE', 'CLOSE_UNESCAPED', 'OPEN_SEXPR', 'CLOSE_SEXPR', 'ID', 'OPEN_BLOCK_PARAMS', 'STRING', 'NUMBER', 'BOOLEAN', 'UNDEFINED', 'NULL', 'DATA', 'SEP', got 'INVALID'
Use Helpers in your app.js add
const exhbs = require('express-handlebars')
var hbs= exhbs.create({
helpers:{
name: ()=>typeof name!="undefined"?name:" "
}
and then in your template add
<input type="text" id="agentsignupname" name="agentsignupname"
class="form-control" value={{name}}""/>
I can't convert this Json to csv. I have been trying with different solutions posted here using panda or other parser but non solved this.
This is a small extract of the big json

I'm running python 3.6 with no restrictions.
I have a dictionary object that is being returned to me from AWS. I need to pull the tag "based_on_ami" out of this dictionary. I have tried converting to a list, but I am new to programming and have not been able to figure out how to access Tags since they are a few levels down in the dictionary.
What is the best way for me to pull that tag out of the dictionary and put it into a variable i can use?

The best way to approach this type of problem is to find the value you're looking for, and then work outwards until you find a solution. You need to look at what is at each of those levels.
So, what are you looking for? You're looking for the Value for based_on_ami's Key. So your final step is going to be:
if obj['Key'] == 'based_on_ami':
# do something with obj['Value'].
But how do you get there? Well, the object is inside of a list, so you'll need to iterate the list:
for tag in <some list>:
if tag['Key'] == 'based_on_ami':
# do something with tag['Value'].
What is that list? It's the list of tags:
for tag in image['Tags']:
if tag['Key'] == 'based_on_ami':
# do something with tag['Value'].
And where are those tags? In an image object that you find in a list:
for image in image_list:
for tag in image['Tags']:
if tag['Key'] == 'based_on_ami':
# do something with tag['Value'].
The image list is the value found at the Images key in your initial dict.
image_list = my_data['Images']
for image in image_list:
for tag in image['Tags']:
if tag['Key'] == 'based_on_ami':
# do something with tag['Value'].
And now you're collecting all of those values, so you'll need a list and you'll need to append to it:
result = []
image_list = my_data['Images']
for image in image_list:
for tag in image['Tags']:
if tag['Key'] == 'based_on_ami':
result.append(tag['Value'])
So, I took your example above, and added another based_on_ami node with the value quack:

I am new in node js.
I am using Express JS and Hogan JS template engine. I know we can not use logic in this template but I need to execute a if statement within for loop statement in view code, to generate table fields.
I tried so many things, Even I follow this links Hogan js also.
But there is only if or for example is give there is no solution for both at a same time.
