            How to Config Javascript ' script in Django?
            Asked 2021-Jun-16 at 02:47

            I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.

            Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.

            I don't have idea why my javascript' script isn't working.

            Run ‘python manage.py collectstatic’ and try again.

            The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.

            I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.

            My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touchs a semaphore file. If the file exists already, it skips the seeds.

            Handle Production Migrations and Development Migrations in Django
            Asked 2021-Jun-15 at 12:28

            While developing a Django project, all your migrations are stored within each app folder, however, in production I don't want those migrations, I want to keep a Production database, and a Development database:

            How do I handle Django migrations in a Production and Development environment?

            I'm asking this question because it's been really hard to update my deployed project with new additions in the development one, my ideal scenario would be to keep each set of migrations in a folder outside my source code, just like the databases.

            ...

            ANSWER

            Answered 2021-Jun-15 at 12:28

            The best idea is to keep production and development migrations the same and while developing you clean migrations before pushing the code and you should push migrations into your Version Control System too.

            In development, you might end up deleting a table and re-creating it so make sure you don't push the un-intended migrations. The thing is you should treat migrations as code, not an automated script. I have done a lot of mistakes in the past, so, I came to the conclusion of including migrations in code. and that's effective and gives more control.

            Moreover you might have to do data migrations in production, how will you do if you wont push the code?

            The Django docs mention DATABASE_ROUTERS and RunPython, but I didn't manage to get it working so far. The function is called, but migrations.CreateModel() has no impact when called from the function: the table is not created.

            Answered 2021-Jun-14 at 16:41

            migrations.CreateModel does not create a model in the database upon instantiation. It is supposed to be present in the operations list where the migrations system will then use it to create the model. Furthermore you shouldn't be writing this migration manually anyway! Just write the code for the model in models.py:

            1. Why do you need to derive from Entity? these are POCO classes.
            2. User and City have one-to-many relationship, right? then City needs to have list of Users.
            3. In one-to-many entities it is typical to have ID field in addition to object itself. So, City would have CountryId.

            Probably, put your DbContext class as well. And "Entity is just a parent with an ID". Huh? and how this ID will be generated - in addition to CityID, CountryID, etc.? You are really asking for trouble

            Advice. I usually create a database with all the tables and foreign keys - and then run scaffolding to get the baseline of objects. Simplifies a lot!

            Then start with that model, and make the needed changes, if any. Based on your code, I am not even sure that you will need any changes!
