Ruby on Rails

Right, which I don't want to do anyway. I'd rather keep it in ActiveRecord

If I try to do a join I get a polymorphic error:

irb(main):122:0> Search.web_search('heather').includes(:searchable).joins(:searchable)
Traceback (most recent call last):
ActiveRecord::EagerLoadPolymorphicError (Cannot eagerly load the polymorphic association :searchable)

@DanL12186

Try the includes after the joins?

I was looking at this just now https://stackoverflow.com/questions/16123492/eager-load-polymorphic

If this is all hyperspecific to Textaculuar/pg_search then forgive me, I've never used them

Tom Cardoso

@tomcardoso

I think it's more a polymorphism issue…

I guess I want to get from a relation of <Search> objects to a relation of its related <Case> objects instead

@DanL12186

Tom Cardoso

@tomcardoso

So that's where I'm banging my head

DanL12186

@DanL12186

Long story short you're basically trying to get a Relation set of Parent.children from a result set of Parents, right?

Tom Cardoso

@tomcardoso

bingo

DanL12186

@DanL12186

I feel like the answer should be obvious, and yet.. lol. Maybe someone'll know.

Tom Cardoso

@tomcardoso

yeah… i've lost a day and a half to this

DanL12186

@DanL12186

Any chance it's a particular item that's failing with the includes and not all of them?

(additionally, this feels like a good time to register my grievance with the fact that it's Array#include? and ActiveRecord#include instead of Array#includes? and ActiveRecord#include...)

Tom Cardoso

@tomcardoso

i've no idea, honestly. i am super out of my depth here

DanL12186

@DanL12186

Just thought maybe you could test it with a query you know is only going to result in 1 or 2 records at a time. What the person was saying on that page was the query probably needed more information in order to eagerly load the association

My thinking may be poor, though :)

did you ever try the includes after the joins?

Tom Cardoso

@tomcardoso

i did… let me try again

yeah:

Search.web_search('heather').joins(:searchable).includes(:searchable)
Traceback (most recent call last):
ActiveRecord::EagerLoadPolymorphicError (Cannot eagerly load the polymorphic association :searchable)

Tom Cardoso

@tomcardoso

Ah, I figured it out! Took a totally different approach that ended up working. Thanks @DanL12186

Which is better to use Rails with, Docker or a Virtual Machine?

@kiti-nomad

Could not find gem 'sqlite3 (~> 1.4) x64-mingw32' in any of the gem sources listed in your Gemfile.
Run bundle install to install missing gems.

how to fix it

Fintan Moloney

@Josebuendia

What happened when you ran bundle install?

Is the gem in your gemfile?

Kiti-nomad

@kiti-nomad

i am newbee

Fintan Moloney

@Josebuendia

Well check your gemfile and run that command.

Kiti-nomad

@kiti-nomad

Fintan Moloney

@Josebuendia

??? Can't help with that!

Kiti-nomad

@kiti-nomad

I don’t really understand the ecology of ruby

So many configurations are not understood

Fintan Moloney

@Josebuendia

Just get pass this road block first.

although i set config.cache_store = :file_store in development.rb nothing is added to tmp/cache folder

Eugeniu Tambur

@RTJ

hi, have you tried:

rails dev:cache

Joseph A.

@matedemorphy

yes

Development mode is now being cached.

i have = render @categories, cached: true in a view

= render 'shared/head_tags', cached: true in application.html.slim

Eugeniu Tambur

@RTJ

config.cache_store = :mem_cache_store
or
config.cache_store = :redis_cache_store
?

Joseph A.

@matedemorphy

= render 'shared/left_sidebar', cached: true
