django-geo | use location-awareness application

I am trying to implement Django Leaflet into my Wagtail app. The underlying form field is a GeoJSON field. I only get it to work properly when registering my model as a snippet not as a Page model, though.

I can add instances of my model based on the Page model and the GeoJSON value is written correctly to the database. I can also edit a features geometry but the geometry won't be displayed on the leaflet map. When Wagtail renders the edit view for the Page based model the GeoJSON turns into a string and deserialization fails:

Prologue:

This is a question arising often in SO:

• Equivalent of PostGIS ST_MakeValid in Django GEOS
• Geodjango: How to Buffer From Point
• Get random point from django PolygonField
• Django custom for complex Func (sql function)

and can be applied to the above as well as in the following:

• Django F expression on datetime objects

I wanted to compose an example on SO Documentation but since it got shut down on August 8, 2017, I will follow the suggestion of this widely upvoted and discussed meta answer and write my example as a self-answered post.

Of course, I would be more than happy to see any different approach as well!!

Question:

Django/GeoDjango has some database functions like Lower() or MakeValid() which can be used like this:

This might be trivial but I can't find the mistake. I'm just getting the initial setup done following the documentation on GitHub. I've started a new app. Installed django-leaflet and django-geojson, created a minimal models.py as well as admin.py.

When I try to place a marker on the map via the admin. Nothing happens, and the icons on the left for drawing markers and polygons is missing.

I must be missing a dependencies, forgot something trivial. But I've been over and over the docs, and I must have stared myself blind.

I haven't created a view or template. Only the model and admin. And migrated the database.

Here is the console log from Chrome and Firefox.

I am not able to use anymore the pip install command to install from a github branch. I was using this line of code for the last 2 years but suddenly it stoped working:

I am trying to upgrade my Django project to Django 2.0, currently the version is 1.8.19. I figured I would do it step by step, firstly upgrading to 1.9, then 1.10 and so on till 2.0. The problem is that I get error message

I am successfully put ssh-key to docker runner and it can git clone to do dependencies installation.

If I use ordinary build-in python manage.py test it works fine. But I am now working with pytest. I can run pytest on ly command line and got results normal.

I am successfully let runner be able to do git clone in order to install Django dependencies. Now I am solving next problem. It is Postgres

My ultimate goal is pytest, but for now I will test gitlab-ci script with python manager.py test.

I am now studying gitlab-ci by copying the simplest case. It has 2 simple steps. They are installation and test without any test case.

My problem:
After I added the SSH_PRIVATE_KEY to the project. pip still unable to install from github.

I had tried putting echo "$SSH_PRIVATE_KEY" to the file. It does show the value in the gitlab terminal.

I'm using django-geoposition in a project and added it to my admin with a GeopositionField() in my models.py.
