Django uploads data from the database directly to the HTML

1, of course, the premise is to set up and configure the Django database ~

2. introduce the required tables in the Python backend function

#要读取home这个APP下的models. py file, introducing the student_message_uneditable and student_message_editable two datasheets
from home.models import student_message_uneditable,student_message_editable

3. Querying data in the Python backend function

# Get a piece of data in the table, using: Table name. objects.get (the query condition (the column name to the left of the equals sign, the right is the specific value))
Student_message_uneditable=student_message_uneditable.objects.get (Student_id=userid)

here,student_message_uneditable is the query to the data, with student_message_uneditable. column name to get the value of the individual data in that piece of data

4 . The value of the variable in the python backend function passes the data to the HTML page
#向前端页面 will be All the variables in the current function are passed to the HTML, directly using Render_to_response () and locals ()
return render_to_response ("student_center.html", Locals ())

4. using Data in HTML pages

Put the acquired data into a text box

<input value="{{ student_message_uneditable. Student_name }}">

Use the obtained data to determine the value of the drop-down box

<select name="Sex" id="Stu_sex" class="Form-control" >
<option {% if student_message_uneditable. Student_sex = = 1%}selected{% endif %}> man </option>
<option {% if student_message_uneditable. Student_sex = = 0%}selected{% endif %}> female </option>
</Select>
