I have a transactions controller and view. When I click to link "Transactions", I show all transactions.
How to add a before display transactions such as enter start and end dates?
What you need is probably the ransack gem.
You can add a custom filtering mechanism in your controller like this:
def index
#q = Transaction.ransack(params[:q])
#transactions = #q.result(distinct: true)
end
and using in the view a simple for like this:
<%= search_form_for #q do |f| %>
<%= f.label :start_date %>
<%= f.search_field :created_at_gteq %>
<%= f.label :end_date %>
<%= f.search_field :created_at_lteq %>
<%= f.submit %>
<% end %>
And this will let you filter the Transaction data using the created_at param as a filter. Modify the form accordingly if you need to filter using another Date/DateTime param from the model.

I am using will_paginate for my Rails project. Depending on 'Post' variable its 'mediatype' attribute I use either memo or photo and show results in different parts of the page. Will_paginate paginates both sides of the website together. If I have done 10 posts: 1 memo, 9 posts of photos, and 1 memo and I want to show 5 results per page, I will see on the front page one memo instead of two, and 4 photos. I use the same variable post and I have two different attributes how to make separate paginations for them? Here is my code. In fact I would like to add 'load more' button. It might a bit too complicated, so I will be satisfied with simple version of pagination. Still if you know how to make 'load more' buttons for two parts of the website, I will much appreciate. Thank you.
INDEX VIEW
<% content_for :memo_content do %>
<%= will_paginate #posts %>
<% #posts.reverse_each do |post| %>
<% if post.mediatype == "Memo" %>
<%= post.mediatype %>:
<%= post.title %>;
<% end %>
<% end %>
<% end %>
<% content_for :media_content do %>
<% #posts.reverse_each do |post| %>
<% if post.mediatype == "Photo" %>
<%= post.mediatype %>:
<%= post.title %>;
<% end %>
<% end %>
<% end %>
POSTS_CONTROLLER
def index
#posts = Post.order(name: :asc).paginate(page: params[:page], per_page: 5)
end
you can get count manually in controller and pass this count to will_paginate
Like:
#posts = Post.order(name: :asc).paginate(page: params[:page], per_page: 5)
from #posts get manually for both memo and posts of photos and pass this count in view.
<%= will_paginate #memo_count, :renderer => BootstrapPagination::Rails %>
<%= will_paginate #posts_of_photos_count, :renderer => BootstrapPagination::Rails %>
I'm using ransack to allow users do dynamical searching:
Controller:
#q = Visit.search(params[:q]);
#visits = #q.result(distinct: true)
#q.build_condition
Model:
def self.ransackable_attributes auth_object = nil
(column_names - UNRANSACKABLE_ATTRIBUTES) + (_ransackers.keys)
end
View:
<%= search_form_for #q, url: doctor_visits_path do |f| %>
<%= f.condition_fields do |c| %>
<%= render "condition_fields", f: c%>
<% end %>
<p><%= link_to_add_fields "Add condition", f, :condition %>
<div class="actions"><%= f.submit "Search", {:class => "btn"} %></div>
<% end %>
Partial:
<div class="field">
<%= f.attribute_fields do |a| %>
<%= a.attribute_select({ associations:
[:specialists, :treatment_factors]
},{:class => "form-control"}) %>
<% end %>
<%= f.predicate_select({},{:class => "form-control"}) %>
<%= f.value_fields do |v| %>
<%= v.text_field :value,{:class => "form-control"} %>
<% end %>
<%= link_to "Remove", '#', class: "remove_fields" %>
</div>
I have several boolean attributes in Visits table. When I choose the boolean attribute in the first field, true or false in second (predicate field) and leave the third value field empty, the params are generated correctly, but the sql query is not, the condition is ignored and all the records from the table are returned instead.
What can be the reason?
Add in your model:
Simple version, using PostgreSQL:
ransacker :predicate do
Arel.sql("to_char(\"#{table_name}\".\"predicate\", '99999')")
end
and the same, using MySQL:
ransacker :predicate do
Arel.sql("CONVERT(#{table_name}.id, CHAR(4))")
end
I have a mongo rails 4 app, with an embedded photo.
I have no problem in the new form, but in the edit form, if the user has not upload any photo, the form will not display a "add photo button".
Here is the form:
<%= f.fields_for :founder_profile_photos do |founder_photo_f| %>
<%= render partial: 'founder_profile_photo_fields', locals: { f: founder_photo_f } %>
<%= link_to_add_association raw('<i class="fi-plus"> add a founder photo</i>'), f, :founder_profile_photos %>
<% end %>
Here is the partial:
<div class="nested-fields">
<% if f.object.file.to_s.empty? %>
<%= f.file_field :file, label: "Upload a founder photo." %>
<% else %>
<%= image_tag f.object.file, class: 'small-10 medium-10 image-previewer' %>
<% end %>
</div>
Thank you so much for your help. I finally found what was wrong, I needed to build the field photo in the edit action of my controller, other the field does not exist and therefore do not appear in the view.
def edit
if #user.photos.empty?
#user.photos.build
end
end
photo is embedded into the user model (one to many relation) if you have a one to one relation you have to do:
if #user.photo.blank?
#user.photo = Photo.new
end
Thank you very much for all your help, still so much to learn.
When a potential User is editing their Profile, they have an option to show/hide some information from public view. I did that with
<div class="field">
<%= f.text_field :contact %>
<%= f.select(:contact_type_id, ContactType.all.map {|l| [l.name, l.id]}) %>
<%= f.check_box :visible %>
<%= f.label :visible, "Vidljivo" %>
<%= f.link_to_remove "Izbriši kontakt" %>
</div>
in a partial that's called in the view like this
<%= f.fields_for :contacts do |l| %>
<%= render 'contacts_form', f: l %>
<% end %>
What I now want is to display on a public profile page only that information that the User marked as visible, and I tried it through a different partial
<div class="field">
<% if :visible == true %>
<%= f.text_field :contact %>
<% end %>
</div>
called from
<%= f.fields_for :contacts do |l| %>
<%= render 'contacts_show', f: l %>
<% end %>
but it doesn't work. I tried tons of variations, but it all came down to guessing the right syntax. How do I display only those entries which visibility is marked as "true"?
Why are you displaying the public profile as a form? If you only want to show the information you can iterate over the contact information of the user where the contact type is visible.
I solved it by using a different approach. In my user controller I defined an instance variable #visible and passed it the array consisting of all database entries that have visible parameter set to true. Then I used #visible.each in the view to print the desired content.
I have a search form on an index page for my Properties model which is using both Ransack and Geocoder to search the Properties model fields as well as narrow the results down based on distance from an address input by the user in the search form.
The address and distance are captured in the form with :nearaddress and :distance, respectively, which I send in params[:near]. I am checking for the presence of them in the controller index action following this answer. The result is “undefined method `merge' for nil:NilClass” when navigating to /properties, so the view will not render. How do I enable these non-model form parameters to be passed to the controller properly? I think this might be a strong parameters issue but I'm stuck on how to permit these attributes that aren't in the Properties model. The error highlights the "f.text_field :nearaddress" line.
index.html.erb:
...form fields that work when excluding the two that follow...
<div class ="field">
<%= f.label :nearaddress, "Address" %>
<%= f.text_field :nearaddress, params[:near] %>
</div>
<div class ="field">
<%= label_tag :distance %>
<%= text_field_tag :distance, params[:near] %> miles
</div>
<div class="actions"><%= f.submit "Search" %></div>
<% end %>
properties_controller.rb:
def index
if params[:near].present? && (params[:near].to_i >0)
#search = Property.near(params[:near]).search(params[:q])
else
#search = Property.search(params[:q])
end
#properties = #search.result(:distinct => true).paginate(:page => params[:page])
...
end
I was able to resolve this problem by removing the "f." and adding "_tag" to the :nearaddress field as well as specifying the params in the controller index:
<%= label_tag :nearaddress, "Near Address" %>
<%= text_field_tag :nearaddress, params[:near] %>
<%= label_tag :distance, "Distance From Address (mi)" %>
<%= text_field_tag :distance, params[:near] %>
<div class="actions"><%= f.submit "Search" %>
<% end %>
if params[:distance].present? && (params[:distance].to_i >0) && params[:nearaddress].present?
#search = Property.near(params[:nearaddress],params[:distance]).search(params[:q])
else
#search = Property.search(params[:q])
end
