will_paginate | Pagination library for Rails and other Ruby applications | Application Framework library

I have a list of users that post reviews. I'm trying to make the list sortable in different ways. I'm stuck on sorting the list by each user's most recent review.

My current approach is to make a model scope. I'm just not getting it.

This is the model:

I have a project with a search feature. I have three classes, Product, Review and User. I have a self.search method in the product model doing a query on all three class tables.

When I put together the search view, It listed the product name, the review author and any text in a review that matches the search string.

Then I thought, lets pretty that up a bit.

So I'm cross referencing the ids to also list user avatars and time stamps and star ratings. But to do that, I'm making local variables searching in all the classes.

So I think there's now quite a code smell here. There is no controller to load up with @users = User.all. I'm sticking with _user = User.find_by types of local variable assignment. The search fingers are now in all class pies.

So my question is really, should my bloated search now rightly to be scaffolded into an actual class? Or is there another approach like a helper? Is it possible this is not that bad of an approach?

Here is my view:

I have cloned an existing project and trying to run it in my system. Since this is the first time I don't have any Gemfile.lock file in my directory. I tried running bundle install and the following errors occur:

I have a blog that uploads banner and thumbnail images. I originally had it set to upload to the local directory using the carrierwave gem and I wanted to try to use digitalocean spaces since the app is deployed to the digitalocean app platform. I am able to get it working on localhost:3000 but when I deploy it to digitalocean it keeps reverting back to a previous deployment saying that a health check failed but not real errors.

I decided to deploy it to heroku since I am able to get actual errors. Here is the current error I get from heroku:

I do not know why this is breaking. I'm trying to run a migration on some code I've inherited and I've hit a snag. Here is the error message followed by the migration file code.

I updated my ruby to 3.0.0 but for some reason now my application doesn't work. I have searched online for different answered but I cannot find anything. This error has gotten me going crazy now. Here is what happens.

When I do bundle update I get:

I am trying to setup a project that uses rails 2.3.2. In my Gemfile I have gem "rails", "2.3.2". Running bundle install outputs Using rails 2.3.2. When I try to run any rails commands, in this case rails s I get a load error.

I am implementing jQuery DataTables in my application based on this tutorial. I could use a packaged Gem, but I need to understand and learn what's underneath.

My purpose is to display the Values from a ValuesList in a way the user can play with the list (search, sort, paginate).

The result fits for purpose, but I still have one issue: when displaying a dataset of 26 records, by pages of 10 records, only the first page contains data. Clicking the Next button returns an empty page (but correctly counts the missing records: "Showing 11 to 20 of 26 entries").

Searching the log, I found out that when first diplaying the page, the request sent to the database is:

Having issue while passing limit per paje display 50 records.
