In this issue, the editor will bring you about the value of a certain column of fields in the Django ORM query table. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Scene:

There is a column in a table, you need to get all the values of this column, how do you do it?

Solution:

There is a model: Event

Method 1: get the content: Event.objects.values ('title')

Output:

The first way is to get a QuerySet, the content is composed of key-value pairs, the key is the column name of the table, and the value is each corresponding value.

Method 2: get the content: Event.objects.values_list ('title')

Output:

Method 2 also gets a QuerySet, but the content is the value of the query column in the form of meta-ancestor.

But what we want is the value of this column, ah, how is this a QuerySet, and also contains the column name, or is included in the meta-ancestor?

Check the high-level usage and tell you how to get the list of a value, such as: ['Test feed',' Today', 'third schedule Test', 'fourth schedule Test', 'Fifth Test schedule']
