i want to add errors / success flash messages globals

[HosMercury]

how to get the flash messages / success msg / errors msg
by having the ability to have globals/locals?

[Keats]

When you say globals, you mean a context that is passed to every render?

[HosMercury]

I mean something is sometimes sent to the( base.html ) like flash messages.
it will always be in the base
it should appear if I send them to a specific page descended from the base.html
otherwise nothing should happen.

so the variable will be in the base.html, not the child page. without that. I have to send that variable with every context which sometimes I do not need to do

there ??
