likeable | Use Redis to make your Ruby | Application Framework library

I am trying to order all the recipes in my database by the number of likes they have received. Likes are polymorphic and belong to :likeable while a recipe has many likes.

My query works for SQLite3, but when I upload to Heroku using PostgreSQL it seems to break things.

function is as follows:

Recipe.select('*').joins(:likes).group('recipes.id').order('COUNT(likes.likeable_id)')

And the error that Heroku gives me when I try to run the website:

Hello great people of SO!

First of all, I'm sorry if my english is not very good, but I'm gonna try my best here to describe my problem

I have 3 Models

1. User
2. Post
3. Like

User.php

Using the following code, getting an error:

I'm working out the output of a model generated with glm. The model output is stored in a nested tibble. I want to calculate confidence interval through the transformation from type = "link" to inverse-link (using $family$linkinv). However, I can't get it to work with dplyr::mutate in a nested tibble because the way of pulling the $family$linkinv is from the model object using model$family$linkinv(x), which seems not to work as intended in the nested format.

This current question is based on a previous question (and chosen answer) I posted about testing the level of liking fruits by different predictors using a linear model. I conduct a research to figure out which fruit is more likeable: mango, banana, or apple. To this end, I go ahead and sample 100 people at random. I ask them to rate, on a scale of 1-5, the degree of liking each of the fruits.

While the previous question had to do with lm, here I'm trying to utilize quasibinomial glm. The issue is that I want to get confidence intervals but my method (glm %>% predict) outputs SE in "link space", therefore I have to go through a conversion process (detailed in this SO answer) to get what I want.

I have 3 models:

Post, Like, Trending

The like and trending models are polymorphs, both are:

I'm trying to select the picture with the most likes from a category the previous day. However, my query returns a null result. My pictures are related to the likes through a has many polymorphic relationship.

Here is my query:

I am trying to select the picture with the most likes within a specific category from my database. I have a database table storing the pictures and a table storing the likes. The pictures table is related to likeable table through a hasMany polymorphic relationship.

Like model:

I want to display all liked products of a specific user from the database, but I'm getting an error Integrity constraint violation: 1052 Column 'deleted_at' in where clause is ambiguous .How can I display all liked products of specific user?

Like.php

I want to use concerns app/controllers/concerns/likeable.rb and app/models/concerns/likeable.rb. The first one goes to controllers and the second one goes to models.

If I create two files, only the first one is loaded.

What's the best way to solve this problem?
