Redmine

Did you find a solution ? even I am facing the same problem

Could you please post a sample plugin crashing?

The file index.api.rsb is in \redmine-2.3.1\plugins\smiles\app\views\timelog

api.array :time_entries, api_meta(:total_count => @entry_count, :offset => @offset, :limit => @limit) do
  @entries.each do |time_entry|
    api.time_entry do

      spent_on = time_entry.spent_on.present? ? time_entry.spent_on.strftime('%d-%m-%Y') : ''
      created_on = time_entry.created_on.present? ? time_entry.created_on.strftime('%d-%m-%Y') : ''
      updated_on = time_entry.updated_on.present? ? time_entry.updated_on.strftime('%d-%m-%Y') : ''

      api.id time_entry.id
      pi.project(:id => time_entry.project_id, :name => time_entry.project.name) unless time_entry.project.nil?
      api.issue(:id => time_entry.issue_id) unless time_entry.issue.nil?
      api.employee(:id => time_entry.user.employee_id) unless time_entry.user.nil?
      api.user(:id => time_entry.user_id, :name => time_entry.user.name) unless time_entry.user.nil?
      api.activity(:id => time_entry.activity_id, :name => time_entry.activity.name) unless time_entry.activity.nil?
      api.hours time_entry.hours
      api.comments time_entry.comments
      api.spent_on spent_on
      api.created_on created_on
      api.updated_on updated_on
      render_api_custom_values time_entry.custom_field_values, api
    end
  end
end

Any update on this?
In my plugin I am overriding both issues/index.api.rsb and issues/show.api.rsb. Its working fine for show.api.rsb but is giving error for index.api.rsb.

After trying out few things I eventually figured out a solution for this. If you are overriding api responses i.e views/issues/index.api.rsb in a plugin, you need to override the html view of that action in the plugin as well. So you just need to copy views/issues/index.html.erb to your plugin views.

cp app/views/issues/index.html.erb plugins/myplugin/app/views/index.html.erb

cp app/views/issues/index.html.erb plugins/myplugin/app/views/index.html.erb

that does work, thanks

Copy/Pasting views/issues/index.html.erb to the plugin views do fix the error, but we should be able to override the API without modifying the HTML view. Any way to fix the original bug?

with redmine 3 you also have to copy/paste views/issues/index.pdf.erb and views/issues/show.pdf.erb :(

Hi! It would be nice if this patch was backported to the 2.6.x branch.
Thank you!

For redmine 2.6, i fixed it by changing one line in redmine_root/config/initializers/10-patches.rb

Change this block of code

class Resolver
    def find_all(name, prefix=nil, partial=false, details={}, key=nil, locals=[])
      cached(key, [name, prefix, partial], details, locals) do
        if details[:formats] & [:xml, :json]
          details = details.dup
          details[:formats] = details[:formats].dup + [:api]
        end
        find_templates(name, prefix, partial, details)
      end
    end
  end

TO

class Resolver
    def find_all(name, prefix=nil, partial=false, details={}, key=nil, locals=[])
      cached(key, [name, prefix, partial], details, locals) do
        if (details[:formats] & [:xml, :json]).any?
          details = details.dup
          details[:formats] = details[:formats].dup + [:api]
        end
        find_templates(name, prefix, partial, details)
      end
    end
  end
