cmdb Asset Management 2

Add assets

Now api service has been able to get to the end we have to do the operation. Additional procedures should be followed after obtaining the corresponding write operation

We need to do is to save the post request is sent over the data to the database. We create a repository name app, and design models create a table to store data. Behind can get information from the database and display it

models.py

We can set this line of business first. Run-table then

We first cert deleted, and the file will be written to comment out here, so that each judge is a new host

Receives service data below, it will be stored in the database

We want to add these asset information stored in the database

Look at the new server, there is a default at 1, at 2 can be empty, we first matter

We look at three hardware information

These three hardware and consistent information, and we pass over the data field name, too

We will take out the data dictionary, and then update to the same dictionary, a synthesis.

Obtained as follows dictionary
