I am having difficulty with gmaps4rails infowindow. I have an app which successfully displays multiple markers using json data stored in activerecord. I created a partial to select additional info to display in the infowindow, but the same data from the first instance of PoliceAlert class is being repeated in each marker:
Controller:
class StaticPagesController < ApplicationController
def main
#police_alerts = PoliceAlert.all
#police_hash = Gmaps4rails.build_markers(#police_alerts) do |police_alert, marker|
marker.lat(police_alert.latitude)
marker.lng(police_alert.longitude)
marker.json({:id => police_alert.id })
marker.picture({
"url" => view_context.image_path('/assets/police.png'),
"width" => 32,
"height" => 37
})
marker.infowindow render_to_string(:partial => '/layouts/police_alerts_infowindow', :locals => { :police_alert => police_alert } )
end
end
Partial:
<% PoliceAlert.find do |police_alert| %>
<%= police_alert.hundred_block_location %>
<br><%= police_alert.event_clearance_description %></br>
<%= police_alert.event_clearance_date %>
<% end %>
How do I get markers to display info for each police_alert? Thanks so much in advance?
Not sure to understand but replace your partial with:
<%= police_alert.hundred_block_location %>
<br/>
<%= police_alert.event_clearance_description %>
<br/>
<%= police_alert.event_clearance_date %>

I have to convert my form to not using nested association. In other words, instead of
<%= link_to_add_association f, :contacts, class: 'btn btn-primary', partial: 'projects/contact_fields', data: {
association_insertion_node: '.contact_fields', association_insertion_method: :append
} do %>
<i class="fas fa-plus"></i>
<% end %>
<%= f.fields_for :contacts do |contact| %>
<%= render 'projects/contact_fields', f: contact %>
<% end %>
I would like to be able to just pass in a string to be used as the container (similar to how you can with field_for).
<%= link_to_add_association 'contacts[]', 'projects/contact_fields', class: 'btn btn-primary', partial: 'projects/contact_fields', data: {
association_insertion_node: '.contact_fields', association_insertion_method: :append
} do %>
<i class="fas fa-plus"></i>
<% end %>
<% #contacts.each_with_index do |contact, index| %>
<%= fields_for "contacts[#{index}]", contact do |c| %>
<%= render 'projects/contact_fields', f: c %>
<% end %>
<% end %>
Cocoon is currently unable to edit/manage a collection. Cocoon is just helping the form-behaviour for nested-children functionality in rails, so there is no simple solution to edit an array or collection. On the other hand, this is in general pretty simple to implement without cocoon.
Very high level, do something like:
#contacts.each do |contact|
= render `contacts/edit`, contact: contact
= render `contacts/new`
so render the edit form for each existing contact, and render an empty new form. You will have to edit your controller functionality a little, because you will always re-render the complete collection/index page (with all existing contacts in the collection?).
So you can just render multiple forms on one page. Using turbolinks this will render fast and feel actually completely the same. You could use xhr to update only specific parts of the page, but to get started that is not even needed.
So I ended up following drifting ruby and using code from the cocoon gem to implement something myself. I hope others can benefit from it. Thank you nathanvda for the cocoon gem which helped me with the code below, really wish I could have used it:
add this to your app/helpers/application_helper.rb
def link_to_add_row(*args, &block)
if block_given?
link_to_add_row(capture(&block), *args)
else
#byebug
name, association, new_object, partial, html_options = *args
html_options ||= {}
html_options[:class] = [html_options[:class], "custom_add_fields"].compact.join(' ')
id = 'NEW_RECORD'
fields = fields_for("#{association}[#{id}]", new_object, child_index: id) do |builder|
#byebug
render( partial, f: builder)
end
fields = CGI.escapeHTML(fields).html_safe
link_to(name, '#', class: html_options[:class], data: {id: id, fields: fields})
end
end
add to your app/assets/application.js
$(document).on('click', '.custom_remove_fields', function(event) {
$(this).prev('input[type=hidden]').val('1');
$(this).closest('tr').hide();
return event.preventDefault();
});
$(document).on('click', '.custom_add_fields', function(event) {
var regexp, time;
time = new Date().getTime();
regexp = new RegExp($(this).data('id'), 'g');
$('.contact_fields').append($(this).data('fields').replace(regexp, time));
return event.preventDefault();
});
In your template you can use the following to render a partial for the collection:
<%= link_to_add_row('contacts', contact.new, 'contact_fields', class: 'btn btn-primary') do %>
<i class="fas fa-plus"></i>
<% end %>
This is how I render the partial with the collections in my template:
<tbody class="contact_fields">
<% #contacts.each_with_index do |contact, index| %>
<%= fields_for "contacts[#{index}]", contact do |c| %>
<%= render 'contact_fields', f: c %>
<% end %>
<% end %>
</tbody>
This is what my contact_fields.html.erb partial looks like.
<tr class="nested-fields">
<td>
<%= f.text_field :fullname, class: 'form-control invoke-contacts-search contact-fullname' %>
</td>
<td>
<%= f.text_field :email, class: 'form-control invoke-contacts-search contact-email' %>
</td>
<td>
<%= f.text_field :phone, class: 'form-control contact-phone' %>
</td>
<td>
<%= f.text_field :department, class: 'form-control contact-department' %>
</td>
<td>
<%= f.text_field :manager, class: 'form-control contact-manager' %>
</td>
<td>
<%= f.hidden_field :id %>
<%= f.hidden_field :_destroy %>
<%= link_to '#', class: 'btn btn-danger custom_remove_fields' do %>
<i class="fas fa-trash-alt"></i>
<% end %>
</td>
</tr>

The problem is you have define #qrreviews = Agentinteraction.where("agent_id = ?", #agent.id) which returns a AR_Relation.
Try changing
#qrreviews = Agentinteraction.where("agent_id = ?", #agent.id)
to
#qrreviews = Agentinteraction.where("agent_id = ?", #agent.id).first
Also
<% form_for #qrreviews, :url => create_qrreview_agents_path do |f| %>
should be
<%= form_for #qrreviews, :url => create_qrreview_agents_path do |f| %>
i have a long list dropdown menu including all currencies, i want the last selected value to be the default selected value in the list.
i am using Rails 4.0.0 and ruby 2.0.0
i am not using a model, i am just using a controller. i have put the dropdown list options inside a helper.
form.html.erb
<div class="calculator">
<%= form_for :convertor, :url => {:controller => "converter", :action => "show" } do |f| %>
<%= f.label :from_currency %>
<%= f.select :from_currency, options_for_select(currencies, :selected => params[:from_currency]) %>
<%= f.text_field :amount, :placeholder => "Amount", id: "textfield" %>
<%= #amount %>
<br>
<%= f.label :to_currency %>
<%= f.select :to_currency, options_for_select(currencies, :selected => params[:to_currency].to_i ) %>
<%= #result %>
<br>
<%= f.submit "Calculate", class: "btn btn-large btn-primary", id: "submitButton" %>
<% end %>
</div>
the list options are loaded from a helper *<%= f.select :to_currency, options_for_select(currencies, :selected => params[:to_currency].to_i ) %>* with name currencies
the dropdown list, in a helper
def currencies
[
['United Arab Emirates Dirham (AED)', 'AED'],
['Netherlands Antillean Guilder (ANG)', 'ANG'],
['Argentine Peso (ARS)', 'ARS'],
['Australian Dollar (A$)', 'AUD'],
['Bangladeshi Taka (BDT)', 'BDT'],
['Bulgarian Lev (BGN)', 'BGN'],
['Bahraini Dinar (BHD)', 'BHD'],
]
end
what am i doing wrong here?
A couple of things:
options_for_select takes two arguments: the list of options and the value that you want selected.
You're passing through the value as a hash: :selected => params...
The parameter name is wrong.
In your controller, you're saying that the parameter is called this:
params[:convertor][:from_currency]
But in your view, you have params[:from_currency].
Therefore, the solution to this is to do this:
<%= f.select :from_currency, options_for_select(currencies, params[:convertor][:from_currency]) %>
This code works for me.
in application helper
module ApplicationHelper
def opts_for_select_cur
opts_for_select = [
['United Arab Emirates Dirham (AED)', 'AED'],
['Netherlands Antillean Guilder (ANG)', 'ANG'],
['Argentine Peso (ARS)', 'ARS'],
['Australian Dollar (A$)', 'AUD'],
['Bangladeshi Taka (BDT)', 'BDT'],
['Bulgarian Lev (BGN)', 'BGN'],
['Bahraini Dinar (BHD)', 'BHD'],
]
return opts_for_select
end
end
and in view
<script type="text/javascript">
$(document).ready(function(){
$('#st').change(function(){
var inputText = $('#st :selected').val();
$("#hidden_one").val(inputText);
$("a").attr("href", "?value="+inputText );
});
$('#aa').click(function(){
var inputText = $('#st :selected').val();
$("a").attr("href", "?value="+inputText );
});
});
<%= f.select :text, options_for_select(opts_for_select_cur, params[:value]), {}, { id: "st" } %>
<br>
<%= link_to "refresh",nil, id: "aa" %>
the result is a select box with selected value.
this can help
<%= f.label :from_currency %>
<% if #from_cur.present? %>
<%= f.select :from_currency, options_for_select(currencies, #from_cur) %>
<% else %>
<%= f.select :from_currency, options_for_select(currencies), :required => true %>
<% end %>
<%= f.text_field :amount, :placeholder => "Amount", :required => true, id: "textfield" %>
<br>
<%= f.label :to_currency %>
<% if #from_cur.present? %>
<%= f.select :to_currency, options_for_select(currencies, #to_cur), :required => true %>
<% else %>
<%= f.select :to_currency, options_for_select(currencies), :required => true %>
<% end %>
i appreciate.
I am trying to figure out what is the best way to go about creating a model like "Article" and another model that is a polymorphic model called "comment". The reason I want to do this is so I don't have duplicate models for comments. So at this point I have the polymorphic model up and running and working with the article model. The problem is I want everything to be on one form. The Ability to edit the article and post a comment. Any suggestions would help me out with this dilemma.
This can be achieved using form_tag
<%= form_tag :url => , :html => {:id=> , :method => , :class => ""} do %>
<% text_field_tag <id>, <default_value>, :name=>"article[title]" %>
<% text_field_tag <id>, <default_value>, :name=>"article[content]" %>
<% text_area_tag <id>, <default_value>, :name=>"comment[id]" %>
<% text_area_tag <id>, <default_value>, :name=>"comment[id+1]" %>
<%= submit_tag 'save' %>
<% end %>
the params will then nicely be grouped in a hash like
{'article' => {'title' => , 'content' => }, 'comment' => {'1' => , '2' => . . .}}
which you can parse to update both the models.
I have this form:
<% #page_title = "Delete Technician: #{#technician.name}" %>
<%= link_to("<< Back to List", {:action => 'list', :id => #technician.id}, :class => 'back-link') %>
<div class="technician delete">
<h2>Delete Technician</h2>
<%= form_for(:technician, :url => {:action => 'destroy', :id => #technician.id}) do |f| %>
<p>Are you sure you want to permanently delete this technician?</p>
<p class="reference-name"><%= #technician.name %></p>
<div class="form-buttons">
<%= submit_tag("Delete Technician") %>
</div>
<% end %>
</div>
when I click on the submit button this is the url that I get:
www.site.com/technicians/1
instead of
www.site.com/technicians/destroy/1
am I not using the form_for helper correctly or is it a configuration somewhere?
You're making this more complicated than it needs to be. There is no reason for a form when a link or a button would do. Why not just this
<p>Are you sure you want to permanently delete this technician</p>
<div> <%= link_to "Delete", technician_path(#technician), :method => :delete %> </div>
That's it.
