Input custom value from parameters to Rails SQL Query - ruby-on-rails

Question

I have written so code to query lists of users who go jogging at a certain time and in certain locations, but I am getting the following error: ActiveRecord::StatementInvalid: SQLite3::SQLException: near "'jogging'"
Does this mean I cannot write a string into that variable? Are there any solutions to this?
users = User.where('ids in (:user_ids)', user_ids:
Activity.where('title :title AND created_at >= :created_at AND location_id: location_id',
{title: 'jogging', created_at: Time.zone.now.beginning_of_day, location_id:
Location.where('id in id', id: user.activities.where.not(location_id: nil)
.order('created_at DESC').first)}))

Answer 1

You can simplified your query this way
location_id = Location.where(
id: user.activities
.where.not(location_id: nil)
.order('created_at DESC').first
)
user_ids = Activity.where("title = ? AND created_at > ? AND location_id = ?",
"jogging", Time.zone.now.beginning_of_day, location_id)
users = User.where(id: user_ids)
But If you want to keep query one liner. You can use this
User.where('id IN(:user_ids)',
user_ids: Activity.where('title = :title AND created_at >= :created_at AND location_id = :location_id', title: 'jogging', created_at: Time.zone.now.beginning_of_day,
location_id: Location.where('id IN(:id)', id: user.activities.where.not(location_id: nil)
.order('created_at DESC').first).ids)
)
Note: I am assuming that you have user object to use above one liner query
Hope this will help you.

I think you forgot to add an = in the query:
Your query:
Activity.where('title :title ...
What you want:
Activity.where('title = :title ...
And if you don't need an operator like > or <, you can also use:
Activity.where(title: title)
If you then need to chain it, it's pretty simple:
Activity.where(title: title).where('foo < ?', 100)
