The same error and traceback occurs on the example repo: https://github.com/pallets/flask/tree/main/examples/celery How can I resolve this? What alternatives are available? Tried moving the class FlaskTask(Task) out of the local scope of the celery_init_app function, but then I obviously lose access to the app variable.
The app.locals object is a JavaScript object, and its properties are local variables within the application. This means you can declare a variable in your app.js with locals and access it within that script or pass it to the response object.
36 In Express 4 You can access to app from req with req.app. See Request object API doc. Locals are available in middleware via req.app.locals (see req.app) In your middleware you could do it as this:
As you mentioned, both req.locals, res.locals or even your own defined key res.userData can be used. However, when using a view engine with Express, you can set intermediate data on res.locals in your middleware, and that data will be available in your view (see this post). It is common practice to set intermediate data inside of middleware on req.locals to avoid overwriting view data in res ...
There are two ways to set a default layout: configuring the view engine's defaultLayout property, or setting Express locals app.locals.layout. The layout into which a view should be rendered can be overridden per-request by assigning a different value to the layout request local.
In your case, as you've exported app, it's perfectly fine to access this at file level (not sure the right term), where you've imported as app.locals.database (remember app is an object). But if you want to access elsewhere where you've not imported, express makes it available to all middleware via req.app.locals.
2 I'm new to nodejs, I'm trying to develop a website with two users, a normal user, and a freelancer. When the user logs in res.locals.currentUser is set as the req.user by using the middleware app.use (I'm using the same middle-ware for both types of user).
I'm trying to understand when it's best to use each of the following. Here is my rudimentary understanding: app.locals -- good for storing global variables at the app level. all users/sessions w...
