(Django)(Important)(Short) How can I roll back DB that changed in unwanted way after renaming fields in models.py
I have a question in Django. I renamed fields in my models.py on my editor. After renaming the name of fields, I made makemigrations and did 'migrate' on cmd. After 'migrate', I checked my database on DB broswer and I found that not only the name of fields changed, but the data of the fields also changed into the name of fields I just changed as just lowercased. i.e.) Original name of field was ingredient and I changed the name to Essential_ingredient. I checked DB and turned out that all of data for the column of changed field is essential_field like picture. Database after renaming fields I posted this question on FB page and one said I can roll back(revert) by doing "migrate ". So I tried it and then it turned out that the field came back correctly to purposedly migrated file, but the data of the field still haven't changed back yet. Database after reverting migrations I guess this problem happened because, when I renamed fields, I renamed two of them at the same time. I saw a comment on stackoverflow that I'm supposed rename the one field at a time, but this was after I'd changed names … -

Django raw query syntax and parameters
What is the correct syntax for raw queries in Django? I always see those easy kind of examples like: lname = 'Doe' connection.execute('SELECT * FROM table WHERE last_name = %s', [lname]) It's awesome how less one parameter explains if you dive into deeper detail! How about: set_var = ((0,'val',3.5),(1,'tadaa',5)) connection.execute("INSERT INTO table VALUES (%s)",[set_var[0]]) or: head = [col1 int(11), col2 int(12), col3 varchar(255)] connection.execute("CREATE TABLE IF NOT EXISTS `%s` %s", [table, '('+str(', '.join(head))+')']) and then there is: query = """SELECT %s FROM special_table""" connection.execute(query, ["*"]) or I could write everyhting simple into a string? connection.execute("SELECT "+injection+" FROM yetAnotherTable") Do I have to use anywhere ';' in the End of the query? And I also saw, that people used {}. format() for querystrings ... And what's the point about backticks? Why shall I not use them? How can I handle a tablename including a "-" ? I'm super confused about the syntax for writing raw queries. Especially about the parameter part. What is allowed? And what is not allowed? Could somebody delight the topic a bit more than the explanations of the Django doc, please! -
How to set environment variables for Django settings.py with Jenkins
I have a settings.py file for my Django project that reads in environment variables for some fields. This works great for local development. I'm not sure of how to make this work for my Jenkins build (Freestyle project). An extra layer of complexity is that some of these variables contain sensitive data (passwords, etc.) and so need to be secured. So far, I have been able to use Credentials Binding Plugin to set up a secret .env file and can successfully access that as an environment variable. How do I go about setting all the 'actual' variables from that file? Or is this bad practice? If it's not bad, wouldn't those variables continue living on the server after the build has finished? If it is bad, what is the better way to do this? I can update the settings.py file easily enough if needed to make this work. -
Bootstrap cards showing on the right side of the page
I want to add 3 cards, but when I try, the cards appear on the right side of the page maybe it is an error on the code before the cards. This is the code of the cards. <div class="card-deck mb-3 text-center"> <div class="card mb-4"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.

Difference between using querying data and creating one through admin page?
I made some models and filled them with fields i.e. CharField and TextField. I registered my model in admin.py so that admin has the ability to create and edit the models in the admin page. Why do people use the terminal shell to query the database rather than using the admin page to simply create it there without the little hassle of importing the model and querying the database in the shell? -

Django raw queries with large params
I feel like going nuts with raw queries. Always Django complains about my misstakes: I try to write a function to copy a table from one database to another.

Django change extablished column with values into a ForeignKey
I have the following model in place: class IssueDescription(models.Model): no = models.CharField(max_length=10, primary_key=True) title = models.CharField(max_length=200, blank=False) confirm = models.TextField() remedy = models.TextField() subsystem = models.CharField(max_length=50, blank=False) It already lives in Postgres DB, and is populated with values. The values held in it came from a .csv file (including subsystem values). What I realized, is that I would like to make subsystem column into a ForeignKey, and move all the values from it into a separate table, e.g.: class Subsystems(models.Model): subsystem = models.CharField(max_length=50, blank=False) class IssueDescription(models.Model): no = models.CharField(max_length=10, primary_key=True) title = models.CharField(max_length=200, blank=False) confirm = models.TextField() remedy = models.TextField() subsystem = models.ForeignKey(Subsystems, on_delete=models.PROTECT, blank=False) What would be the cleanest way of moving already established values in the original IssueDescription model's subsystem column to a newly created Subsystems table, and drawing all the links via ForeignKey field in a new IssueDescription model? -
Django-Filters , Django-tables autocomplete search
Im quite new to django so not very familiar with things. Im trying to autocomplete one of the files and clients filters for django-tables. I was trying to use django-autocomplete-light ( dal).

The returning row count reflecting the rows changed differs. Trigger is removed and Update is performed. Row count = 1 The Trigger is created with a select statement . Row count = -1 however a row has changed A trigger is created with an update statement to randomly change an attribute in updated row. This also returns … -
