Laravel Nova - Map database json column to field

问题

I have a database model with json column type called attributes. This column will contain additional details of the model.

For example: attributes : {'desc' : 'test', 'width' : '500'}.

I would like to display individual attribute (desc & width) in attributes column as a html field in Laravel admin resource.

I checked supported field types and doesn't seem supports.

Any suggestions how I can do this?

回答1:

I'm not sure if it's the recommended answer but i've found a way that should work for you.

Use an Eloquent Mutator: Eloquent Mutators

Then you define a getDescAttribute and a setDescAttribute and pass it in nova like a property on the model like so:

Text::make('Desc', 'desc')

Hope this helps.

Here's how I was able to accomplish this in Nova 2.0. In my case I have a JSON column called fields. In the model, fields is cast to an array.

protected $casts = [
    'fields' => 'array'
];

Then in the resource, the column is mapped using the -> operator.

Text::make('Name', 'fields->name')

Try this. It's the only mention of "JSON" in nova fields description.

回答4:

For example the value for 'desc' column is something like :

"{attributes : {'desc' : 'test', 'width' : '500'}}"

You can directly put it in table format :

KeyValue::make('Desc', 'desc**.attributes**')

Hope this helps
