QUESTION
I am trying to run a program using docker that will allow me to destroy requests by using a program called PostMan to do this I have set up a class named ProductViewSet which will allow me to delete a query. But when I run docker-compose up in my Visual Studio Terminal and try to run a DELETE query through PostMan it gives me an error in PostMan that says "detail": method "DELETE" not allowed. I have tried to use the @action function to try and link the destroy function from my views.py to my urls.py in the same folder using this answer Method Delete Not Allowed - destroy() method Django, I have also tried to just use my main function Product and use a router as seen in this answer "detail": "method \delete\ not allowed" django but both of these answers do not help me at all.
Here is my error that I am getting in PostMan and in my Visual Studio Terminal:

QUESTION
I have a search bar that is searching in 2 models columns title, body, short_description. I am.using MySQL database. Right now, I am using Q lookups but there are some search limitations that I'd like to 'improve'.
One of them is that Q lookups find only results based only on phrase results that are exactly the same as in field so for instance, I have the title why python is so amazing? and I must write why or python or python is in order to get results. What I'd like to get is to extend the search bar to work in the following way:
A user inserts a question in the search bar: python language and search lookup is splitting each word and returning all objects that contain python or language. In the end the result would return object with why python is so amazing?, no matter it user puts python language or amazing python.
I am posting my current code below:
views.py
...ANSWER
Answered 2022-Mar-05 at 19:54I ran into the same issue, and solved it by adding a custom search manager in models.py, above my model. The manager has two methods, one for single word searches, another for multi-word. The query string is split into a list of words using the .split(), (see the view) below.

QUESTION
I have a database of articles that I want to search through. I had been using normal Django ORM to search, which was getting way to slow and then I got to know a little about Indexes in Django. I'm using MySQL and I now know that with MYSQL I cannot put an index field into a TextField as described here in this stack question which I was facing. However in my case I can't change this to CharField.
I was reading through the MyQSL Docs which stated
MySQL cannot index LONGTEXT columns specified without a prefix length on the key part, and prefix lengths are not permitted in functional key parts.
Hence I was of the understanding that since TextField in Django is LONGTEXT for MYSQL, I came across this Django-MySQL package here and thought that using this if I could change the LONGTEXT to a MEDIUMTEXT using this package, this might get resolved. So my updated model I did this
ANSWER
Answered 2022-Feb-19 at 20:31All of these related types, TEXT, MEDIUMTEXT, and LONGTEXT, are too large to be indexed without specifying a prefix. An index prefix means that only the first N characters of the string are included in the index. Like this:

InnoDB doesn't make changes to full text indexes until commits. You can use TransactionTestCase to get around this.
