headmaster | Natural Language Processing for easy dev automation

Your scenario is very practical which makes the question very interesting. But It would be nice for you to look at this documentation.

Use claims to give the teach access to the information they must be able to access. You can save a claim as .i.e. "TeacherName-TargetInforNameTheyCanAccess"; you can have as many claims as possible depending on how much information should be accessible by the teacher.

This goes the same for Students as well. You can create claims for Students that are under that Lecturers Class. Like say: "StudentName-LectureName" an you can then base your authentication by checking if the student is claimed to be under a specific lecturers class.

What I get from your question is that, you want to give read, write for /teachers/{teacher}/classes/{class} to some users with headmaster role.

For that, first you need to check which users are headmasters.

If your teachers doc id is same as userid created in firebase auth, you can add a data field to your teacher document named isHM and set this to true, if user is headmaster:

There was another function that was manipulating the links, I just reapplied the click method afterwards.

You're very close with this - Rails actually expects the foreign key to reflect the name of the associated object's class + _id, in this case contact_id, rather than using the name of the association itself (in this case school_contact).

This gives you two options here: you can rename the column in your db, or you can add the foreign_key option to your association.

For example:

Try below expression:

Try :

The trick is to isolate a br node first, then get the preceding or following text node. So to get the text node containing "Shelburne Road":

I think this is a matter of how you relate the Teacher and School models. If a Teacher can related to multiple Schools, Then there will be ManyToMany relationship between them.

In the form it is not ideal to let the user type the School name, since there can be mistakes when entering it. Best way is to provide a drop-down list to select the School. Then you don't have to ask the user the fill in the unique code of the School.

You need to validate the Teacher if he/she belongs to the School mentioned when applying. Then you have to first get the relevant School object and find if the given Teacher (by name) is a valid foreign key of Teacher.

You can do the validation of the form two ways.

1. Validate at form submission: Here full form is submitted and validated for your condition. If this fails return the form again with the error messages.

2. Ajax call: When the user has finished entering the School name and his/her name (Not a good idea anyway since there can be mistakes when typing) validate the Teacher with an Ajax call with the server.

You can add a function to the modeladmin to return the related user's username
