How do I post into database the input form form fields

[x_marine]

Hi, 

I have been working on a project that works with prefilled form fields in html. 

I wonder how this can integrated into Django Models and posted into the database via view validation.

The value I get from javascritpt computation whic works well.  

My form is like this this.

<form  name="myForm" action="#" method="post">

Price: <input    type="text" id="demo9"  value="3212t" ><br>

Cost:  <input    type="text" id="demo5" value="675" ><br>

Margins:  <input    type="text" id="demo6" value="453" >

<input type="submit" value="Submit">

</form>
