I want to set `import_id` of one category manually, to be able to import remaining topics from an old forum.

I tried this in `rails c` but it does not seem to work:

```plaintext
[11] pry(main)> Category.find(3).custom_fields
=> {}
[12] pry(main)> Category.find(3).custom_fields['import_id'] = '50'
=> "50"
[13] pry(main)> Category.find(3).custom_fields
=> {}

```

I think you need to do something like

```
 CategoryCustomField.create(category_id: 3,...) 

```

Look at the code in the importers for an example.

Yeah, finally found it.

```ruby
    new_category.custom_fields["import_id"] = import_id if import_id
    new_category.save!

```

So looks like I just need to call `save` 🙂

I got confused because for `SiteSetting` it is not needed.

```plaintext
[14] pry(main)> c = Category.find(3)
=> #<Category:0x000056548fd948a8
 id: 3,
...
[15] pry(main)> c.custom_fields['import_id'] = '50'
=> "50"
[16] pry(main)> c.custom_fields
=> {"import_id"=>"50"}
[17] pry(main)> c.save!
=> true
[18] pry(main)> Category.find(3).custom_fields
=> {"import_id"=>"50"}

```
