I do this the following way:

* Start the rails console in test environment in sandbox mode.

        rails console -e test --sandbox

You need this for two reasons:

1. Any changes you do are rolled back.
2. If you already have some seed data it might happen that the factories will start the serialization of attributes from 1, but these records might already exist.

Then in the console:

* Require FactoryBot (was called FactoryGirl):

        require &#39;factory_bot&#39;

* Load the factory definitions:

        FactoryBot.find_definitions

* Include the FactoryBot methods to avoid prefixing all calls to FB with `FactoryBot` (`create` instead of `FactoryBot.create`):

        include FactoryBot::Syntax::Methods

P.S. For [fabrication gem](http://www.fabricationgem.org/) you can load the definitions in the rails console with:

    Fabrication.manager.load_definitions

Also `require &#39;faker&#39;` if you use it.


To solve this problem ensure that the factory bot gem is specifed in your Gemfile similar to this

    group :development, :test do
      gem &#39;factory_bot_rails&#39;
    end

Then `bundle install`.

This should make FactoryBot class available in the development console.

Hope this helps.

You need to `require &#39;factory_bot_rails&#39;`, which is the actual gem that&#39;s being used by Rails. That gem will include the Factory Bot library, making `FactoryBot` available.

You can either do this, or update your Gemfile to require it at startup as in muttonlamb&#39;s answer.

If you want to have it available each time you start the console, you can add this piece of code to the top of your config/environments/development.rb:

```ruby
require &#39;factory_bot_rails&#39;
require &#39;faker&#39; # if you&#39;re also using faker gem
require &#39;rails/console/helpers&#39;
Rails::ConsoleMethods.prepend(FactoryBot::Syntax::Methods)

```

Now you can use the built-in helpers right after starting the console, for example:

```ruby
company = create(:company)
```

I have a layout hidden from the view. On a button click I want it to slide up from the bottom pushing the entire screen contents upwards, very similar to how whatsapp shows emoticons panel in chat screen. 

I have seen SlidingDrawer, that dosen&#39;t work for me. It requires an image as an handle which is shown at the center of the screen, I don&#39;t want that. It also slides over the existing screen content, I am looking for a way to move the existing content upwards.

**Update 1:**

I tried using the animations as suggested by Sanket Kachhela. But the hidden layout is never shown. Here is the code.

**Layout (activity_main.xml):**
&lt;RelativeLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    xmlns:tools=&quot;http://schemas.android.com/tools&quot;
    android:layout_width=&quot;match_parent&quot;
    android:layout_height=&quot;match_parent&quot;
    android:paddingBottom=&quot;@dimen/activity_vertical_margin&quot;
    android:paddingLeft=&quot;@dimen/activity_horizontal_margin&quot;
    android:paddingRight=&quot;@dimen/activity_horizontal_margin&quot;
    android:paddingTop=&quot;@dimen/activity_vertical_margin&quot;
    tools:context=&quot;.MainActivity&quot; &gt;
    
    &lt;RelativeLayout
        android:id=&quot;@+id/main_screen&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot; &gt;
	
	    &lt;TextView
	        android:layout_width=&quot;wrap_content&quot;
	        android:layout_height=&quot;wrap_content&quot;
	        android:text=&quot;@string/hello_world&quot; 
	        android:layout_alignParentTop=&quot;true&quot;/&gt;
	    
		 &lt;TextView
		   android:layout_width=&quot;wrap_content&quot;
		   android:layout_height=&quot;wrap_content&quot;
		   android:text=&quot;@string/hello_world&quot; 
		   android:layout_centerInParent=&quot;true&quot;/&gt;
	        
	    &lt;Button
			android:layout_width=&quot;wrap_content&quot;
			android:layout_height=&quot;wrap_content&quot;
			android:text=&quot;Slide up / down&quot;
			android:layout_alignParentBottom=&quot;true&quot; 
			android:onClick=&quot;slideUpDown&quot;/&gt;
    
	&lt;/RelativeLayout&gt;
	
    &lt;RelativeLayout
        android:id=&quot;@+id/hidden_panel&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;wrap_content&quot; 
        android:layout_below=&quot;@id/main_screen&quot;&gt;
	
        &lt;Button
            android:layout_width=&quot;wrap_content&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:text=&quot;@string/app_name&quot; /&gt;

    &lt;/RelativeLayout&gt;

&lt;/RelativeLayout&gt;

**Activity (MainActivity.java):**

    package com.example.slideuplayout;

    import android.app.Activity;
    import android.os.Bundle;
    import android.view.Menu;
    import android.view.View;
    import android.view.ViewGroup;
    import android.view.animation.Animation;
    import android.view.animation.AnimationUtils;

    public class MainActivity extends Activity {
	
	private ViewGroup hiddenPanel;
	private boolean isPanelShown;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
		hiddenPanel.setVisibility(View.INVISIBLE);
		isPanelShown = false;
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
	
	public void slideUpDown(final View view) {
		if(!isPanelShown) {
			// Show the panel
			Animation bottomUp = AnimationUtils.loadAnimation(this,
		            R.anim.bottom_up);
		
			hiddenPanel.startAnimation(bottomUp);
			hiddenPanel.setVisibility(View.VISIBLE);
			isPanelShown = true;
		}
		else {
			// Hide the Panel
			Animation bottomDown = AnimationUtils.loadAnimation(this,
		            R.anim.bottom_down);
		
			hiddenPanel.startAnimation(bottomDown);
			hiddenPanel.setVisibility(View.INVISIBLE);
			isPanelShown = false;
		}
	}

    }

**Animations:**

bottom_up.xml:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
     &lt;set xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;translate 
	       android:fromYDelta=&quot;75%p&quot;
	       android:toYDelta=&quot;0%p&quot;
	       android:fillAfter=&quot;true&quot;
	       android:duration=&quot;500&quot; /&gt;
    &lt;/set&gt;

bottom_down.xml:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
     &lt;set xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
	&lt;translate 
	    android:fromYDelta=&quot;0%p&quot;

	    android:interpolator=&quot;@android:anim/linear_interpolator&quot;
	    android:duration=&quot;500&quot; /&gt;
    &lt;/set&gt;


Any ideas how this can be done ?

Thanks.

I want to create a two dimensional array in Javascript where I&#39;m going to store coordinates (x,y). I don&#39;t know yet how many pairs of coordinates I will have because they will be dynamically generated by user input.

Example of pre-defined 2d array:

    var Arr=[[1,2],[3,4],[5,6]];

I guess I can use the PUSH method to add a new record at the end of the array. 

How do I declare an empty two dimensional array so that when I use my first Arr.push() it will be added to the index 0, and every next record written by push will take the next index?

This is probably very easy to do, I&#39;m just a newbie with JS, and I would appreciate if someone could write a short working code snippet that I could examine. Thanks

I am using rails console in the development environment and I want to use factories.  How can I get access to them?

I have tried `require &quot;FactoryGirl&quot;` which returns

    LoadError: cannot load such file -- FactoryGirl

I am working on an app that allows Members to take a survey (Member has a one to many relationship with Response). Response holds the member_id, question_id, and their answer. 

The survey is submitted all or nothing, so if there are any records in the Response table for that Member they have completed the survey.

My question is, how do I re-write the query below so that it actually  works? In SQL this would be a prime candidate for the EXISTS keyword.

     def surveys_completed
        members.where(responses: !nil ).count
     end

&gt; RelatedList.has_many :contents declaration are deprecated: :order.
&gt; Please use a scope block instead. For example, the following: has_many
&gt; :spam_comments, conditions: { spam: true }, class_name: &#39;Comment&#39;
&gt; should be rewritten as the following: has_many :spam_comments, -&gt; {

I have spent the better part of the day trying to get images to load on my heroku app.  Everything I try works locally, but not after being deployed to heroku.  

I have png files saved in the images folder under my assets.  I am referencing these images with syntax in my css such as;

    #signin {
      background: url(&lt;%= asset_path &#39;sf.png&#39; %&gt;);
      background-size: 100%;
    }

In heroku when I inspect the background the assets/sf.png link is there but when you click it it shows a broken image, suggesting it did not load properly.

I&#39;ve tried toggling `config.serve_static_assets = false` in the `production.rb` file between true and false and neither works.  

I also have  

    group :production do
      gem &#39;pg&#39;
      gem &#39;rails_12factor&#39;
    end

Precompile is always successful.

and i need to permit hash array in my code. 
based on [manuals][1] I&#39;ve tried like these:

    &gt; params.require(:post).permit(:files) # does not work
    &gt; params.require(:post).permit(:files =&gt; {}) # does not work, empty hash as result
    &gt; params.require(:post).permit! # works, but all params are enabled

How to make it correctly?

In one of my RSpec test, I am creating multiple objects from the same factory definition

Eg

    FactoryBot.create(:model_1)
    FactoryBot.create(:model_1)
    FactoryBot.create(:model_1)

Is there a method that `factory_bot` provides to do this in one line

I know that I can do

    3.times {FactoryBot.create(:model_1)}

But I am looking for something that `factory_bot` provides for creating multiple objects of the same model.

[Note: FactoryBot was originally named FactoryGirl][1]

What is the purpose of `transient do` in FactoryBot factories?

I&#39;ve seen a lot of factories that begin with something like below. 

    factory :car do
      owner nil
      other_attribute nil
    end
    ...

I&#39;ve found some information on this blog:  
[Using FactoryGirl to easily create complex data sets in Rails](https://web.archive.org/web/20180403000920/http://blog.thefrontiergroup.com.au/2014/12/using-factorygirl-easily-create-complex-data-sets-rails/)

But I still don&#39;t fully understand how and why to do this. My experience with FactoryBot is minimal.

Could anyone with some experience using FactoryBot share some insight?
