Calling an ajax request to view a JSON pyramid structure

Question

Calling an ajax request to view a JSON pyramid structure

My experience with ajax is limited, so I would appreciate detailed answers.

I have a Pyramid application where I need to load information via ajax instead of pre-loading it due to feasibility issues. I want to retrieve the necessary information through a pyramid view but I'm unsure of the process.
The data I need is stored in a MySQL database, so I believe I need to import the mouse click event object ajax_id into views.py to execute the query. (I can successfully obtain ajax_id)

In my views.py file, I currently have:

@view_config(route_name="info_ajax",renderer="json")
def info_ajax(self):

    #For this example, let's assume we are returning information from the mouse click event
    A = ajax_id      #represents the id of the mouse click event
    B = ajax_name    #represents the name of the mouse click event

    return {
                'a' : A,
                'b' : B,
        }

Typically, I preload all the necessary information, but that approach is time-consuming in this scenario. Therefore, I cannot simply list MySQL queries in views.py and then include

<script>window.coords = ${a|query_list};</script>

in my .mak file.

I aim to import variables a and b in my JavaScript code for future use without having to reload them when required. How can I achieve this?

After some trial and error, I finally cracked the code:

In my views.py file for the pyramid framework:

@view_config(route_name="info_data",renderer="json")
def info_data(self):

    # Let's say we want to retrieve information from a mouse click event

    click_id = self.request.POST.get('click_event_id')    
    click_name = self.request.POST.get('click_event_name')   

    return {
                'EventID' : click_id,
                'EventName' : click_name,
        }

And in our JavaScript file:

    $.ajax({
        type: "POST",
        url: "details",
        dataType: "json",
        data: {
            'click_event_id': eventID,
            'click_event_name': eventName,
        },
        success: function(data) {
                returned_value = data.EventID;
            }, 
    })
