Hey @AhmedMedDev. Thanks for your contribution. can you add some tests so I can see the implications of this feature?

@AhmedMedDev As packages is growing, It is crucial to submit new pull requests with relevant test cases.

I am quite skeptical about using the '->' symbol in query strings. Although '->' works with the 'where' clause, we need to manually change other query constraints. For example, if we need to find a JSON column (array) that contains a value, we have to use 'whereJsonContains', etc.

This would be a useful feature with proper implementation.

@Lakshan-Madushanka I appreciate your review, could you provide some guidance on how you think these features should be implemented more effectively?

• Step 1:
  We need to find a way to internally identify JSON columns (which is not difficult with Laravel). Allowing the "->" symbol opens up a potential SQL injection vulnerability. This is the major reason why we have validated column names. Eloquent uses PDO behind the scenes, and PDO can only bind values, not column names. So, in your case, the following is possible:
  ?filter[name->;drop * from users;]=10.

• Step 2:
  Implement JSON related filters here.

• Step 3:
  Forward JSON columns to related JSON filters.
