Lets say I have installed a 3rd party app called 'articles', the app contains basic templates and views. And there is a view called 'home' to list articles.
I need to add a form within that view and of course the form variable is not in the default 'home' view. How should I go about adding the form variable to that view?
There are a couple of ways I can think of right now:
Create another app and create a custom view.
This seems crazy and I won't do it, but for the sake of possibility, add a context processor to add the form variable into the context.
Just wondering if anyone had this situation and what is the best approach for this?
well, you may want to try a Function Decorator to redefine the previous view function.
the context processor or the middlerware is not recommend because it's global and dirty.
another use way I can thing is use-defined tags. This may takes more affort and go against the origin design of the tags. But it seem to be a good way.

I have a lot of apps running on my site and I was wanting to make all the views accept a certain kwarg without having to go in and edit them all manually? Is there a way to do this?
I suppose I should add it into the django base view class somewhere, but I am unsure exactly where to add it to in that?
Any ideas?
EDIT:
What I am trying to do is have translations set in my db under a certain model and then have the site default text areas be displayed in a certain language based on the url...
/eng/some/url
/esp/some/url
those two urls would display different languages, but I have to capture the variable and put it into each and every view which is quite cumbersome
Django already has some i18n support in urls, check it out. You need to activate django.middleware.locale.LocaleMiddleware by adding it to your settings.MIDDLEWARE_CLASSES and to tune your urlconf a bit by wrapping your urls with i18n_patterns.
The complete example is given in the docs, I see no sense copying it here.
I am wondering how one would setup a multi-step form in CFWheels.
Clearly I would need to store form data in the session etc as I go, but I would like to know the best approach from a wheels perspective to do this the 'wheels way'.
Do I have just one action in my controller that handles this? Or would it be best to seperate each part of the form out into separate actions?
Advise on this and possible code examples would be much appreciated.
Thanks,
Michael
The way I've done it in past is use Ajax calls and a jquery modal.
though the jquery modal is not important, I just like the aesthetic. a simple div replacement will also work.
If you cannot be sure that the users can use AJAX then it won't work for you, but you might be able to use a popup window.
The advantage of using Ajax calls for multi-step forms is that you can adjust the form content from one step to another. Another advantage is that you don't have to store user data in the cache or session. Because each time you send a form, you can use the POST or GET.
For this to work, the quickest way of setting this up is to use the plugin called RemoteFormHelpers. Then each step of the form would be a different controller (or the same one with a switch statement based on the data passed)
I think this is a pretty versatile way of doing this, but you cannot do a form that uses file-uploads, well not easily as ajax won't let you do it without some serious pain.
I am trying to learn Coldbox to perhaps replace the current framework I am using. One of the features that I currently use is the ability to override any of the template inclusions by convention.
Essentially, lets say I have a view, "views/home.cfm"
<h1>I am the default theme</h1>
and that is all well and good. But lets say that I have a different view, "themes/[theme-name]/views/home.cfm"
<h1>I am the user chosen theme</h1>
that I want to include conditionally (say there is a cookie to determine what theme is in use). Also, if the file does not exist, the default/fallback view should be rendered.
Is there any way of doing this overriding the system functions?
I looked at interceptors, and the preViewRender and postViewRender interceptors seem like the place to do something like this, but there doesn't seem to be any way of manipulating the actual workflow. If seems to be mainly pre/post processing of the content. For instance, there doesn't seem to be a way to "return false" to tell the renderView method to not actually render the view. Or any way to affect the location in which the view is to be found.
Any ideas?
Tyler,
The ColdBox Framework is quite flexible. It is possible to do what you desire but I don't think modifying renderView() is the best way to resolve this--although, you most definitely can.
I would encourage you to create a User Defined Function in the /includes/helpers/ApplicationHelper.cfm file that contains the logic you require. The functions that are added to this helper file are accessible from anywhere in the framework. This would allow you to create a function called "renderSkin()" that contains the logic you need. RenderSkin() would ultimitly call "renderView()" when you finally figured out which template you wanted to render for that user.
Respectfully,

I would suggest you go with the interceptor route, but change the layout instead of the view.
From the postEvent interceptor you can get the processedEvent key from the interceptData to change the layout.
Otherwise you could just make the check part of the layout page. The layout can the be a switch statement (or a more OO approach) $including the themed layout files as needed. This has the advantage of giving you a chance to emit custom interception points and having common functionality (css, js)
I'm doing a form application (similar to django-contact-form) and would like to be able to insert the rendered form in a Django template of another application.
What's the best way to do that? Should I create a template for the form (with for example only {{ form.as_p)? If so how can I insert it in another template?
Thanks

What do you mean when you say a separate 'application'? Do you mean a completely separate Django site, or just a separate app within your current site?
If the latter, there's no issue: just import the form into the view you want to use it in.
If the former, then there isn't really any good way to do it. You could try using an iframe within your template to point to the external site, but it's not a particularly nice architecture.
Couldn't you load the application with the form you need in the settings.py file under INSTALLED_APPS and then call it from your template somehow? I'm a little new to django, but from what I can tell that seems like it would be the "django" way of doing it.
I'm working on a Django site with a basic three column design. Left column navigation, center column content and right column URL specific content blocks.
My question is about the best method of controlling the URL specific content blocks in the right column.
I am thinking of something along the lines of the Flatpages app that will make the content available to the template context if the URL matches a pre-determined pattern (perhaps regex?).
Does anyone know if such an app already exists?
If not, I am looking for some advice about the best way to implement it. Particularly in relation to the matching of patterns to the current URL. Is there any good way to re-use parts of the Django URL dispatcher for this use?
Django CMS is a good suggestion, it depends on how deep you want to go. If this is just the beginning of different sorts of dynamic content you want then you should go that way for sure.
A simple one-off solution would be something like this:
You would just need to write a view and add some variables on the end of the URL that would define what showed up there. Depending on how fancy you need to get, you could just create a simple models, and just map the view to the model key
www.example.com/content/sidecontent/jokes/
so if "jokes" was your block of variable sidecontent (one of many in your sides model instances) the urls.py entry for that would be
(r'^content/sidecontent/(?P<side>)/$,sides.views.showsides),
and then in your sides app you have a view with a
def showsides(request, side):
Sides.objects.get(pk=side)
etc...
For something like this I personally would use Django CMS. It's like flatpages on steroids.
Django CMS has a concept of Pages, Templates, and Plugins. Each page has an associated template. Templates have placeholders where you can insert different plugins. Plugins are like mini-applications that can have dynamic model-based content.
Although Django-CMS is an interesting suggestion, there are quite a few projects that do specifically what you've requested - render blocks of content based on a URL. The main one that I know about is django-flatblocks.
