What is the IForm equivalent to fileAFormOpt? - haskell

I want to use runInputPost on an existing form with a file input tag. fileAFormOpt exists for AForms, but how can I do the same with an IForm since there is no fileField type?

I would recommend using lookupFile for that use case.

How do you extend a library created variable in onvif python?

onvif python will create base variables from WSDL but not the optional elements. How do I add the optional variables to the existing definition?
as in a = create(sometype)
This defines the elements a.b and a.c.
I need to add elements a.c.d, a.c.e.g and a.c.e.h.
The short answer: It depends on what the existing variable is.
The longer answer: Since the existing variable is defined by a third party library with little to no visibility, run the code under a debugger that will tell you what the existing variable is, e.g, list, dict, etc. From that information look in the python documentation if you are not familiar with that type of variable.

In Play Framework 1.2.x, how to use a render arg value in a path expression?

Let's say that I have a renderArg named xyz. In the groovy template, what's the syntax for using the value of the renderArg in a path expression?
For example:
href="##{'/public/stylesheets/whatever/${xyz}.css'}"
The above fails with a template compilation error (which is what I expected, really). How can I use the value of the render arg inside the path string?
I'll also need to use the arg in other path expressions (not just for a css file reference).
You cannot do it directly, but there is one workaround:
First you should have defined route to root of the application, for instance:
GET / Application.index
next you can use it in this way:
href="##{Application.index}public/stylesheets/whatever/${xyz}.css"
If you repeat the structure above very often, then you can use custom tag, to do so:
add file /app/views/tags/customlink.html(customlink is name of the tag, you can use another one),
fill the content:
##{Application.index}public/stylesheet/whatever/${_key}.css
You can use it now in this way:
href="#{customlink key:'xyz' /}"
More about custom tags you can read here

expression engine dynamic variable names: {slide_{index}_title}

I am using a simple looping plugin so that my template looks like this:
{exp:loop_plus start="1" end="4" increment="1"}
<h3>{slide_{index}_title}</h3>
{/exp:loop_plus}
However, I am ending up with the following output:
<h3>{slide_1_title}</h3>
<h3>{slide_2_title}</h3>
<h3>{slide_3_title}</h3>
<h3>{slide_4_title}</h3>
Is there any way I can have dynamic variable names like this? I am not looking for alternative methods for building a slider, I simply would like to know if the dynamic variable names like this is possible. Thanks!
I'm assuming that Loop Plus (http://devot-ee.com/add-ons/loop-plus) sets the {index} part, so the question is what is defining {slide_1_title}...?
Assuming you have an entry field or variable with this defined, what you have is correct, but if it's not working, it means there's a parsing order issue.
Let's assume the code you supplied is wrapped in a {exp:channel:entries} tag pair, what happens is EE will try to parse the variable first, so will see: {slide_{index}_title} which doesn't exist. The {exp:loop_plus} add-on will then parse it, converting it to {slide_1_title} (but to late as channel:entries has already tried to parse it), which is what is finally output to the template.
So what you want to ensure is that EE parses {exp:loop_plus} before {exp:channel:entries}, do this using parse="inward" tag:
{exp:loop_plus start="1" end="4" increment="1" parse="inward"}
<h3>{slide_{index}_title}</h3>
{/exp:loop_plus}
This is a global EE parameter that EE uses to control parse order - you won't find it documented under the specific add-on. By adding the parameter, it means this child tag will get parsed before it's parent.
One way you could do it is to declare a preload_replace variable in your template and use it in your custom field name.
So something like:
{preload_replace:my_var_prefix="whatever"}
And then in your loop, you could then use:
{slide_{my_var_prefix}_title}

Can you ignore case while using replace?

Pretty self explanatory. For example, I would want both test and Test to be replaced:
{{ var|replace({"test": 'replaced'}, ignore) }}
The replace filter is defined as a wrapper for strtr, so there's no built-in way to do that.
Extending twig is easy! Simply create a new filter called ireplace (or something else you find appropriate) that uses str_ireplace in the background.
I think this function is used to replace keywords, not to do a search and replace

What is the use of SPHttpUtility.NoEncode method?

Does anybody know what is the usefulness of the SPHttpUtility.NoEncode method? It seems like it takes a string as parameters and returns it without any modification.
Is there a case where you can use this and I'm missing it?
The data in sharepoint that is markup content has to be encoded so that it can be passed around in xml without it breaking.
for example & lt;a / & gt; instead of "< a/ >" (without the spaces)
Therefore if you want to ouput the rendered instead of >a /< you use the NoEncode function to convert it to valid xml.
Hope that makes sense.
