How to get foreign key value instead of key in an ExtJS grid, using Django models?

Asked 2019-Apr-21 at 15:00

I'm creating a simple 'task manager' web application using Django 1.11 and ExtJS4 as a client side.

Each user created entry will have its own category. Now i have a problem - in the ExtJS grid, every category of an entry displaying as an 'id' value of category. And this is fair because i use Foreign key to id.

How can i display a type field instead of id in the ExtJS grid table?

I've tried to use django 'to_field = type' option and it's actually works, instead of 'category_id = id', i got a 'category_id = type'. But my teacher said that it's not a solution for this case and at backend part i should operate with an 'id'.

On your queryset you could specify the values you want from the database inside the .values() and then you'll have a list of objects. E.g list_of_entries = Entry.objects.all().values('headline', 'category__id', 'foo', 'bar')

ExtJS4 - Outline appearing around Submit button for form

I have a fileuploadfield button that has an outline of a white box appearing behind it. Is there a way to remove this?

It seems to only be an issue in Extjs4.

Since you must have the fileuploadfield inside a form, my workaround was to use a bodyStyle configuration in the form, set the background-color to transparent, and a margin-top to re-center the fileuploadfield.

ExtJs-> Ext.Store.proxy.writer error: No type specified for writer.create

Asked 2018-May-17 at 08:27

So I have upgraded from extjs4 to extjs6 and this store always have this error:

No type specified for writer.create

This code has two uses:

For getting the data for the initial page
For getting the data for whenever a button is clicked.

Whenever I comment out the proxy.writer code portion, it will produce the data for the initial page. But whenever I won't comment it out, it will not get the data for the initial page. And it will also return this error whenever I clicked a button:

Uncaught TypeError: items.slice is not a function

So my question is, is the writer portion have wrong syntax or something since it is updated to extjs6?

P.S. I tried to change the this.callOverridden to this.callParent since it states that the this.callOverridden is already deprecated, still has the same error.

Yes, you are using override in a way that may have worked in ExtJS 4 but is AFAIK unsupported across all versions of ExtJS.

What you want to do is define your custom writer as a new class:

I would like to understand how to remove the event listeners which are added by class as shown below (remove event for div#mainMenu)

I have tried all available methods but none to my avail. Also I dont see this issue in the extJS4.x version but only in 3.4 version. Any plain JS code to handle this?

You can use getEventListeners function to get listeners map of an element. After that use removeEventListener method, to remove event from element. You can use this function to remove all events from an element.

How to undo the row added in the grid of extjs

Asked 2017-Mar-30 at 08:34

I want to how can we undo the specific being added in the grid before actually saving it .

Please have a look at this

I 've added two rows but since for eg: for some validations failures the second row is not valid so I want to undo the second row but keeping the first dirty for the saving of that data to the db.

What i was trying is I was pushing all the dirty rows to an array and then updating in the database. But I don't know how to undo or delete the invalid row being added. Without reloading the grid Example for reference Live example

You shouldn't have to push the rows into an array for synchronization. What you really want to use is the methods available on the underlying store and/or model.

To reject the second model and update all other ones in the database, two lines suffice. The exact code may differ depending on the Ext version; in ExtJS 6.2.1, it would be:

grid.getStore().getAt(1).reject() (or .drop())
grid.getStore().sync()

while the generalized approach would be to reject all invalid models:
