$('#records_table').append("<%=j :partial => 'partials/gallery_items' %>"); 
$('#div_next_link').html("<%=j render :partial =>  'partials/next_link' %>");
Pagy.init(document.getElementById('container'));

like this?

@ddnexus

yes sir

Ben

@yosupgurl

sorry man, i'm just so confused. I've tried so many things at this point

Uncaught Error: Module build failed (from ./node_modules/rails-erb-loader/index.js):
Error: rails-erb-loader failed with code: 1

Domizio Demichelis

@ddnexus

ok, so please, debug that first

but it's better you start new with the example or you will never get it done

Ben

@yosupgurl

Mhhm, i've created a separate app for debugging. My issue lies somewhere with the rails-erb-loader.

I can render .erb just not .erb partials in the JS.

Domizio Demichelis

@ddnexus

rails erb loader is part of webpack

Ben

@yosupgurl

thnx for the help though.

Domizio Demichelis

@ddnexus

replace the erb line wih the actual content to try

but add the export and global too

I will have time tomorrow. good luck

@elmoren

Am I able to set the total count when calling pagy() manually? I'm using pagy with a handful of aggregations, and when I do order by aggregation, pagy's count query says that aggregation doesn't exist

I might just end up using Countless

Nathan Elmore

@elmoren

I found the info I needed in the "Paginate any Collection" of your docs. Sorry about that

@andymilk

Is it possible to use pagy_countless with pagy_searchkick?

Domizio Demichelis

@ddnexus

pagy_searchkick gets the count from the searchkick results object that already contains the total_count, so pagy_countless is kind of pointless

Domizio Demichelis

@ddnexus

the total_count gets it from response["hits"]["total"], hence whatever is there, has already been fetched by the time pagy gets it. pagy does not query the DB: that's the reason it's pointless

andymilk

@andymilk

thanks!

@yosupgurl

hey, is there a way to retrieve the value for the current page? I'd like to display different content based on current page.

Hi. I use pagy_url_for to make links like items/page/3, but trim extra doesn't work for this, I still have /page/1 in browser url. Without pagy_url_for it works fine. How to solve this problem? Thank you.

Domizio Demichelis

@ddnexus

Indeed the trim extra expects a query string param. You should take a look at the trim extra code and change the regular expression according to your custom url. It will be simpler than what the extra.

@nikitapashinsky

hey! how could one add classes directly (inline) to the <%== link.call(item) %>, or the <%= item %>?

I'm using Tailwind and would like to keep utilities inline, and I want to style the link directly to make the click area bigger (using padding).

I was able to add classes to previous and next buttons as follows: <%== link.call(pagy.prev, "&lsaquo; Previous", 'class="p-4 ... "' %>, but I can't do the same with link.call(item).

Everything I write after item, for example: link.call(item, 'class="p-4"') is rendered directly on the page... Would appreciate your help. Thank you!

Hi! I'm using pagy_bootstrap_nav_js. Is there anyway to custom the template like pagy_bootstrap_nav? https://github.com/ddnexus/pagy/blob/master/lib/templates/bootstrap_nav.html.slim

    def pagy_bootstrap_nav_js(pagy, id=pagy_id)
      link, p_prev, p_next = pagy_link_proc(pagy, 'class="page-link"'), pagy.prev, pagy.next
      tags = { 'before' => p_prev ? %(<ul class="pagination"><li class="page-item prev">#{link.call p_prev, pagy_t('pagy.nav.prev'), 'aria-label="previous"'}</li>)
                                  : %(<ul class="pagination"><li class="page-item prev disabled"><a href="#" class="page-link">#{pagy_t('pagy.nav.prev')}</a></li>),
               'link'   => %(<li class="page-item">#{mark = link.call(PAGE_PLACEHOLDER)}</li>),
               'active' => %(<li class="page-item active">#{mark}</li>),
               'gap'    => %(<li class="page-item gap disabled"><a href="#" class="page-link">#{pagy_t('pagy.nav.gap')}</a></li>),
               'after'  => p_next ? %(<li class="page-item next">#{link.call p_next, pagy_t('pagy.nav.next'), 'aria-label="next"'}</li></ul>)
                                  : %(<li class="page-item next disabled"><a href="#" class="page-link">#{pagy_t('pagy.nav.next')}</a></li></ul>) }
      %(<nav id="#{id}" class="pagy-bootstrap-nav-js" role="navigation" aria-label="pager"></nav>#{pagy_json_tag(:nav, id, tags, pagy.sequels, defined?(TRIM) && pagy.vars[:page_param])})
    end

checked the source code. Do i need to override this method?

Domizio Demichelis

@ddnexus

There is no template for the *_jshelpers. In theory you could write your own but it will be slower and more complex to write than just override the helper method, as you guessed.

Hello everyone!
I'm building a watchlist app on rails, using Tmdb API.
Basically I'd like to search for movies, and have the results displaying 20 movies per page.
I'm also using the 'themoviedb-api' gem, which allows me to use the following in my controller (for exemple for Harry potter)

Tmdb::Search.movie("Harry Potter")

which will give back :

#<Tmdb::Result page=1, total_pages=23, total_results=446, results=[#<Tmdb::Movie adult=false, backdrop_path="/hziiv14OpD73u9gAak4XDDfBKa2.jpg", genre_ids=[12, 14], id=671, original_language="en", original_title="Harry Potter and the Philosopher's Stone", overview="Harry Potter has lived under the stairs at his aunt and uncle's house his whole life. But on his 11th birthday, he learns he's a powerful wizard -- with a place waiting for him at the Hogwarts School of Witchcraft and Wizardry. As he learns to harness his newfound powers with the help of the school's kindly headmaster, Harry uncovers the truth about his parents' deaths -- and about the villain who's to blame.", popularity=144.218, poster_path="/wuMc08IPKEatf9rnMNXvIDxqP4W.jpg", release_date="2001-11-16", title="Harry Potter and the Philosopher's Stone", video=false, vote_average=7.9, vote_count=19723>

So there are already the page, total_pages in the API answer, but I don't know how to exploit them.
I tried to do

@pagy, @movies = pagy(Tmdb::Search.movie(params[:query]))

But it seems to suits only for model saved in DB. In my case the Movies are API calls

Thanks

Domizio Demichelis

@ddnexus

Indeed, the pagyvanilla constructor is for AR collections. In case you have already the count and the current page, you have to do the inverse process.

Domizio Demichelis

@ddnexus

Something like:

tobj = Tmdb::Search.movie("Harry Potter")
@pagy = Pagy.new(count: tobj.total_results, page: tobj.page)
@movies = tobj.results

should mimic what the pagy constructor does

please, confirm whether that works, because if it does, I am going to add this very example to the doc

potatosalad94

@potatosalad94

I've tried it but it seems that @movies still shows the result array of the first page, no matter which page i'm accessing.
I also tried to use the Array Extra, by doing to following in my controller:

      movies = Tmdb::Search.movie(params[:query])
      @pagy_a, @movies = pagy_array(movies.results, count: movies.total_results, page: movies.page)

But the same is happening, always showing me the first page array

Domizio Demichelis

@ddnexus

that probably means that you don't use the page param for the search

potatosalad94

@potatosalad94

normally to access page 2 with the tmdb gem, it would be :

Tmdb::Search.movie(params[:query], page: 2)

Domizio Demichelis

@ddnexus

if you just do Tmdb::Search.movie("Harry Potter") again and again, you ar3e getting always the first page. How are you supposed to pass the page to Tmdb::Search?

so you have to do Tmdb::Search.movie(params[:query], page: params[:page])

Domizio Demichelis

@ddnexus

does that work?

potatosalad94

@potatosalad94

Yes ! Finally it worked ! No need for the Array Extra, your first solution was the one. Was just missing the page params. Thanks a lot :)

Domizio Demichelis

@ddnexus

great then... I will probably use the example in the documentation somewhere

Domizio Demichelis

@ddnexus

example added: Paginate collections with metadata

thank you

Andy Qin

@andylouisqin

hello all! I see that pagy handles overflow nicely, but what's the best way to configure "underflow" behavior, e.g. page < 1. I'd like it to return an empty page as well

Andy Qin

@andylouisqin

(I've answered my own question. Will be rescuing from this error)

Domizio Demichelis

@ddnexus

Yes Andy, here is another bit about handling exceptions. And if you are using rescue_from ArgumentError be aware of the gotcha at the end of the page.
