General error: 1364 Field 'name' doesn't have a default value

@Tray2 the problem is not in the database name how you can see in categoryresource is required so the name is present but not pass for saving in the load we have "data.name": "dsadas", "data.description": "dsada", "data.categories": 3 but why get null on save dont now

@KalimeroMK Trust me, I work with databases every day and that error means that you are attempting to insert a null value in the name field, and since it doesn't have a default value, it throws that exact error. You need to make sure that you pass the name to the database.

@Tray2 I understand what you are talking but you dont understand me I pass category name

"data.name": "dsadas",
 "data.description": "<p>dsada</p>",
 "data.categories": 3

form the form but still tray to inser null value this is the problem if filed is requerd cenot be null if a enter name for the category whay it trai to insert null values this is my question and problem

@KalimeroMK exactly, you are passing a null value to the database.

@Tray2 thet is my question way it pass null value when i put nema for the category

Also you didn't show the full model. Maybe there is a mutator?
