Controller to Ajax Function AND View

[Gualter Portella]

Hi everyone,

I currently have a function in the default.py controller like the one below:

def overview():

    some code goes here

   

    return dict(income=json(income), form=form, bank=bank)

The first  variable is passed to the javascript tag in order to render a chart trough Chart.js

The last two variables are passed to the body of the view in order to render a form and generate a bank integer argument to redirect to a different controller/function upon clicking on an <a> tag.

As it is, everything is working great.

I was just wondering whether there is a way to make the first variable be retrieved by an AJAX function while the two others be sent to the view.

I can do it by creating two functions like these, but I need everything in the same controller:

def json_function():

     some code here

     

     return response.json(income)

def overview():

    some code goes here

   

    return dict(form=form, bank=bank)

    

   

Can I write these actions in just one controller?

My intention is to update the chart through an Ajax call without refreshing the page.

Many thanks.

Cheers,

[Anthony]

If you just want to avoid duplicating code to create the "income" variable, you could simply extract that into a separate function and call it from within each of the two controller actions. If you really want to have a single controller action for both the initial full page load and for subsequent Ajax updates, you can do something like this:

def overview():
    income = [some code]
    if request.ajax:
        return response.json(income)
    [more code]
    return dict(income=json(income), form=form, bank=bank)

Great, Anthony.

I will give it a try and let you know the result.

Thanks.
