I am trying to display all the metrics in a table format with an edit option. But, I end up with the below error

In Index view, I am able to see all the data. But when I click on edit link, it is not redirecting to edit view where I have different columns to be showed.

index view:

<%= form_for :metrics_controller, url: metrics_path(@metric), method: :get do |f| %>
 <table id="metrics">
 <thead>
 <tr id="AllMetricColumnNames">
 <th id="CommentsColumn">Comments</th>
 <th id="EditColumn">Edit</th>
 </tr>
 </thead>
 <% @metricAll.each do |data| %>
 <tr id="AllMetricValues">
 <td id="Comments"><%= data.Comments %></td>
 <td id="EditButton"><%= link_to "Edit", edit_metric_path(@metricAll) %></td>
 <% end %>
 </tr>
 </table>
<% end %>

Controller:

class MetricsController < ApplicationController
 def index
 @metricAll = Metric.all
 end

 def show
 @metric = Metric.find(params[:id])
 end

 def edit
 @metric = Metric.find(params[:id])
 end

 private def post_params
 params.require(:metric).permit(:Metric, :Comments)
 end
end

routes:

 root 'metrics#index'
 get 'index' => 'metrics#index'
 get 'edit' => 'metrics#edit'
 resources :metrics

You're passing ALL the metrics for the edit route. Move from

<td id="EditButton"><%= link_to "Edit", edit_metric_path(@metricAll) %></td>

to

<td id="EditButton"><%= link_to "Edit", edit_metric_path(data) %></td>

data is the current metric in your code

According to your screenshot, the error is within the model.
Also, as mentioned by others, you should remove those get routes as the resources :metrics will generate the necessary routes for all your CRUD actions a.ka. for the index, show, edit, new, create, update, destroy.

My guess is that the metric.rb file has a belongs_to :automated_thresholding relationship but the metrics database table is missing the field automated_thresholding_id.

You should create a migration to add that field

add_reference :metrics, :automated_thresholding
