Quickly making the Application read only

[Drazen D. Babic]

Hi, 

in the app folder create ro.html and modify jam/server_clases.py

.

.

    def apply_changes(self, data, safe, file_name=None):
        result = None
        changes, params = data
        file_name = 'ro.html'
        if os.path.exists(file_name):
            self.abort(u'This is a demo version with limited functionality. \
                You are not allowed to write changes to the database. \
                The full-featured version is located in the demo folder of the Jam.py package.')

        else:

            if not params:
                params = {}
            delta = self.delta(changes)
            if self.task.on_apply:
                result = self.task.on_apply(self, delta, params)
            if result is None and self.on_apply:
                result = self.on_apply(self, delta, params)
            if result is None:
                result = self.apply_delta(delta, safe)
            return result

.

.

Now the app is read only. Remove ro.html, and it is not read only.

No need to restart the app.

This is useful for example for restricting updates after 5pm :)

I hope the new Jam will have similar by default (for builder.html too).

For V7,

file items.py add:

    def apply_changes(self, data, safe, connection=None):
        result = None
        result_data = None

        file_name = 'ro.html'
        if os.path.exists(file_name):
            self.abort(u'This is a demo version with limited functionality. \

                You are not allowed to write changes to the database.')
        else:
