QUESTION
I recently added a package to my project and did a pip freeze > requirements.txt
afterwards. I then did pip install -r requirements.txt
to my local and it added a sidebar.
I did a pip install -r requirements.txt
to the server as well and it produced a different result. It's sidebar was messed up.
I tried removing the sidebar by doing this answer but it did not get removed.
...ANSWER
Answered 2021-May-31 at 03:01First of all, this navbar is added by Django 3.1+
and not by any other 3rd part packages.
Copy & Pasting from Django 3.X admin showing all models in a new navbar,
From the django-3.1 release notes,
The admin now has a sidebar on larger screens for easier navigation. It is enabled by default but can be disabled by using a custom AdminSite and setting
AdminSite.enable_nav_sidebar
toFalse
.
So, this is a feature that added in Django 3.1 and can be removed by settings AdminSite.enable_nav_sidebar = False
(see How to customize AdminSite
class)
You don't have to edit any CSS or HTML file to fix the styling, because Django comes with a new set of CSS and HTML, which usually fix the issue. (That is, it is not recommended to alter the styling file only for this)
If that doesn't work for you, it might be because of your browser cache.

I am trying to deploy my Python app on Heroku, but have been unsuccessful. It seems that a problem is occurring with the PyICU
package, which I'm unsure how to correct. I've confirmed that this is the only issue with my deployment; when I remove PyICU
from my requirements file, everything works. But of course my site can't work without it.
Can anyone please guide me in how to correctly install this package on Heroku? I've tried various methods, including downloading the .whl file and then adding that to my requirements file, but then I get another error:
ERROR: PyICU-2.7.3-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform.
I don't understand why - it's the correct Python and os version.
Here are the relevant excerpts from the build log:

wheel.
You can also try pyicu-binary

I've written a function that requests some data from an API and dumps it in a Storage Account. Then I'm accesing the data in Azure SQL DB using this method. Everything works as intended, but I'm left with the following looking table:
...ANSWER
Answered 2021-May-27 at 14:31If you wanted to put it into separate tables, you would use SCOPE_IDENTITY
to get the previous insert's ID.
Because the root object is in an array, you need to change the path to $[0]
QUESTION
I'm adding the django-import-export to the admin in my app.
One thing I wanted to do was to offer the possibility of selecting in the admin page of selecting which fields to export.
I searched for this topic but I only came across two questions with no answers.
Is it possible to add the possibility to dynamically choose which fields to export from the admin page?
Thanks.
...ANSWER
Answered 2021-May-22 at 20:09Yes this is achievable, but it is a little tricky. Take a look at the example application, and get this working first.
- Take a look at the
BookAdmin
implementation. - Create a subclass of
ExportForm
, which implements a form widget which can read the list of fields to export. - Add a
BookResource
constructor which can take aform_fields
as a kwarg, and save this as an instance variable. - In
BookAdmin
, Overrideget_export_resource_kwargs()
methods to return the list of fields from the form. - Override
get_export_fields()
ofBookResource
to return the list of fields extracted from your form. - Finally, you'll have to override
export_action()
so that it creates an instance of your custom form. (You actually only need to override the line which instantiates the form - there should be aget_export_form()
method for this, so that the whole method doesn't need to be overridden. Feel free to submit a PR.)
Try this out with the example application before porting to your own app.
Example:(based on admin.py
)

QUESTION
I've been using Octobercms for a while and have read documentation about exporting data as csv. However nothing is mentioned a single thing about exporting file with a dynamic name because I needed to append text or set a filename with a date. Is this a sort of limitation with Octobercms?
...ANSWER
Answered 2021-May-08 at 12:31For this, you need to override the default behavior.
In your controller where you added
Backend.Behaviors.ImportExportController
ImportExport Behavior
, you can add thedownload
method, and there you can change the name of downloading the CSV file.

We saw https://developer.shopware.com/docs/guides/integrations-api but couldn't find a detailed documentation of the APIs.
EDIT: I found https://my-shop-host.example/api/v2/_info/swagger.html which describes all available APIs and import-export-file
endpoints, but it is not clearly described how to use them (and which ones to use).
I believe we need to call (extracted from the admin panel work flow)
- /api/v2/_action/import-export/prepare
and then
- /api/v2/_action/import-export/process
to trigger an import.
But how are the files uploaded?
Is there an easier way, for example in one call?

QUESTION
I am using the Django-import-export(version 2.5.0) module in Django(version 3.1.4). So I am able to import all my models fields except for the ForeignKey field. I don't know how to make this one work. Can you look at my code and see what is wrong or needs to change? I need Django Admin to import the ForeignKey field.
models.py
...ANSWER
Answered 2021-Apr-28 at 04:12I don't have the reputation points to be able to add a comment but I think the issue you're experencing is due to your model's field naming conventions.
Since your foreign key relation inside the SitePart
to Agency
is called system_no
, your SitePartResource
's ForeignKey Widget isn't referencing the correct field - it's referencing the related Agency
model instance (which I believe is why you aren't getting any errors on import but the value is not being displayed).
To fix this, you just neeed to change the ForeignKey widget to reference the related Agency object's system_no
field (not the instance itself). I haven't tested it but changing your FK field to something like the following should work!

Answered 2021-Apr-09 at 10:04There are a couple of approaches you could take. The approach you choose might depend on whether this is a "one-off" or if you need a reusable class. I would probably favour 'method 2'.
Method 1You could filter the queryset in your view, and then pass this to export:
