How to look out for particular value in the For loop of the Phoenix HTML.
Like I only want to fetch out the 2nd candidate_pipeline from the @candidate_pipelines. How to do that? Your response will be highly appreciable. Note- Inside my for loop, the variable are depended on candidate_pipeline.
<%= for candidate_pipeline <- @candidate_pipelines do %>
<%= form_for get_candidate_update_changeset(candidate_pipeline), "#", [class: "d-inline", phx_change: "update_candidate_stage"], fn f -> %>
<input type="hidden" value="<%= candidate_pipeline.id %>" name="candidate_id"/>
<%= select f, :job_stage_id, Enum.map(@job_stages, &{&1.name, &1.id}), [class: "custom-select custom-select-sm"] %>
<% end %>
<% end %>

Look for the part about “filters”.
ycv005
Can you give me example to how to fetch out nth index value from the For Loop?
LostKobrakai
You can’t but you can use
Enum.with_indexto add indexes to your list of items.ycv005
I have used the
Enum.atbut the problem is that I can’t then use the attribute of the candidate_pipe. For example, then I can’t use the candidate_pipeline.id. Could you solve the above part either by anyway? Note- I have the index value.Or there is something like this-
<%= candidate_pipeline = @candidate_pipelines[index] %>. So that values which will be stores into the variable and further I can access attribute values like candidate_pipeline.id.kokolegorille
It is not the functional way to proceed.
There are no loops, and using index to get Enum.at is not really efficient.
Something like taking each 2 elements should be done with filter.
What do You really want to do?
ycv005
I want to fetch out the particular element present at a index value from @candidate_pipelines to a variable. With the help of this variable I can access value like variable.attribute. Mainly, I want to access all parameter that are available at the particular index value of the @candidate_pipelines.
kokolegorille
When You use for, each element of @candidate_pipelines is going to be treated. You don’t need to lookup with an index, because it should be the current element.
Or did I miss something?
ycv005
That’s what I have done- iterating over the enumerable but I want only 1 at a time that is present at a index, don’t want to iterate over list/enumerable.
kokolegorille
You already get one element at a time with this.
ycv005
Yes, You are right but the problem is that I don’t want other values. It is wastage of time, resource and unwanted value are getting as output. For example- I want only 2nd element but it is iterating over the whole due to which extra data from other index are geeting as output which I don’t want.
