Everyone likes celebrities, right? Well, even if you don't, now is your chance to create your own, better, fictional celebrities! Let's create an Express app with all the basic CRUD actions that will allow the user to create their own celebrities and edit them as they see fit.

The user should be able to:

1. See the list of celebrities
2. See the details of a celebrity
3. Add new celebrities
4. Update existing celebrities
5. Delete celebrities

But wait! That's not all!

Once we have our celebrities, we need something for them to do! Let's make up some movie ideas for our celebrities to star in.
That means we'll need all the basic CRUD actions for movies as well.

The user should be able to:

6. See the list of movies.
7. See the details of a movie.
8. Add new movies.
9. Update existing movies.
10. Delete movies.\

• Fork this repo
• Clone this repo

• Upon completion, run the following commands:

$ git add .
$ git commit -m "done"
$ git push origin master

• Create Pull Request so your TAs can check up your work.

After forking and cloning the project, you will have to add a starter_code/.env file:

PORT=3000

And you have to install all the dependencies:

$ cd starter_code
$ npm install

Now you are ready to start 🚀

Once we have generated our Express app, our first step is to create the Celebrity model and seed some initial celebrities in our database.

The Celebrity model should have:

• name - String (like Tom Cruise, Beyonce, Daffy Duck, etc.)
• occupation - String (what the celebrity does, why they are famous. For example actor, singer, comedian, or you can put unknown if your celebrity is someone like Kim Kardashian)
• catchPhrase - String (every celebrity needs a good catch phrase. Well maybe not all of them have one in real life, but all of our celebrities will have a catch phrase. This can be pretty much anything)

1. Create the celebrity.js model file in the models/ folder.
2. In the celebrity.js model file:
   • Create the Celebrity model with the schema.
   • Create the celebrity schema with name, occupation and catchPhrase.
   • Export the Celebrity model.
3. Create the seeds.js file in the bin/ folder.
4. In seeds.js file:
   • Create an array of 3 objects, each with name, occupation and catchPhrase for our initial celebrities.
   • Call the Celebrity model's create method with the array as argument.
   • In the create method's callback, display feedback.
5. Run the seed file with node to seed your database.
6. Check the database with the mongo command to confirm that your data was saved.

Now that we've got some celebrities in the database, we can start working with them in our Express app. Let's display a list of all the celebrities.

Here's the route we will be using:

1. Locate the /celebrities GET route in routes/celebrities.js.
2. In the route callback:
   • Call the Celebrity model's find method to retrieve all the celebrities.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/index view.
   • Pass the array of celebrities into the view as a variable.
3. Create the celebrities/ folder inside views/.
4. Create the index.hbs view file inside the views/celebrities/ folder.
5. In the views/celebrities/index.hbs view file:
   • Add an <h2> tag for the page's heading.
   • Use a forEach loop to display tags with each celebrity's name.
6. In the views/index.hbs (homepage) file:
   • Add a link that goes to the /celebrities route.

We've got a list of celebrities that displays each of their name, but what if we want to see the other details? In our views/celebrities/index.hbs view with our list of celebrities, let's add links so that the user can click on any celebrity's name, and go to a page specifically for that celebrity. On this page, we will show all the details of that celebrity.

Here's the route we will be using:

1. Create the /celebrities/:id GET route in routes/celebrities.js.
2. In the route callback:
   • Call the Celebrity model's findOne or findById method to retrieve the details of a specific celebrity by its id.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/show view.
   • Pass the variable with the celebrity's details into the view.
3. Create the show.hbs view file inside the views/celebrities/ folder.
4. In the views/celebrities/show.hbs view file:
   • Add an <h2> for the page's heading.
   • Display tags with the celebrity's name, occupation and catchPhrase.
5. In the views/celebrities/index.hbs view file:
   • As part of the loop that displays each celebrity's name, add a link that goes to the /celebrities/:id route with the :id replaced by the actual celebrity's id.

Now that we have a list of celebrities, as well as a personalized details page for each celebrity, let's make it so the user can add new celebrities to the database

1. Locate the /celebrities/new GET route in routes/celebrities.js:
2. In that route's callback:

• Render the celebrities/new view.

3. Create the new.hbs view file inside the views/celebrities folder
4. In the views/celebrities/new.hbs view file:
   • Add an <h2> for the page's heading.
   • Add a <form> tag that makes a POST request to /celebrities.
   • Add <input> tags inside the form so the user can fill in values for each attribute of the celebrity. Make an input for name, occupation, and catchPhrase
   • Add a <button> tag in the form so the user can submit the form once they are done filling it out.
5. Locate the /celebrities post route in routes/celebrities.js.
6. In that route's callback:
   • Create an object with keys for name, occupation, and catchPhrase.
   • Values for those keys should come from the form (req.body is the object full of the values from the form)
   • Create an instance of the Celebrity model with the object you made in the previous step
   • Call the save method to save the new celebrity to the database
   • If there is an error, render the celebrities/new view so the user can try again.
   • If there is no error, redirect to the page with the list of celebrities
7. In the views/celebrities/index.hbs view file:
   • Add a link that goes to the page you just created with the form to create a new celebrity.

Now that we have a list of celebrities, a celebrity details page, and a page to create new celebrities, we only have 2 features left to implement: editing celebrities and deleting them. Since deleting is simpler, let's start with that.

1. In the views/celebrities/index.hbs file:
   • As part of the loop, add a <form> tag that makes a POST request to celebrities/:id/delete where the :id is replaced by the actual id of each celebrity.
   • Add a <button> tag inside the form so that it can be submitted.
2. Create the /celebrities/:id/delete POST route in your routes/celebrities.js file
3. In that route's callback:
   • Use the Celebrity model's findByIdAndRemove method to delete the celebrity by its id.
   • If there's an error, call the route's next function and return the error
   • If there is no error, redirect to the list of celebrities page.

Final piece of our CRUD puzzle: editing existing celebrities.

Here are the routes we will be using:

1. Create the /celebrities/:id/edit GET route in routes/celebrities.js.
2. In that route's callback:
   • Call the Celebrity model’s findOne or findById method to retrieve a specific celebrity by its id.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/edit view.
   • Pass the variable with the celebrity’s details into the view.
3. Create the edit.hbs view file inside the views/celebrities/ folder.
4. In the views/celebrities/edit.hbs view file:
   • Add an <h2> tag for the page's heading.
   • Add a <form> tag that makes a POST request to /celebrities/:id with the :id replaced by the actual celebrity's id.
   • Add <input> tags inside the form for each attirbute of the celebrity.
     • Bonus: When you render the edit form, make sure each of the input fields is pre-filled with the current value of the attribute for that celebrity
   • Add a <button> tag inside the form so that the user can submit the form once they are done editing.
5. Locate the /celebrities/:id POST route in the routes/celebrities.js file.
6. In that route's callback:
   • Create an object with keys for each attribute of a celebrity (celebrity has 3 attributes. What were they again? Look back and review if you forgot.)
   • Values for those keys should come from the form submission (req.body).
   • Call the Celebrity model’s update method and use the celebrity's id to specify which celebrity we are updating. Also, use the object you just created with the updated attributes for the celebrity and pass this object into the update method as the second argument.
   • If there is an error retrieving that celebrity, call the route's next function and return the error
   • If there is no error, redirect back to the list of celebrities.

At this point, we have implemented all the basic CRUD actions for the Celebrity model in our app. Nice work!

Now that we've done all this good work, it's time to add the Movie model. After all, what's the point of having all these celebrities if we can't make up fake movies to cast them in?

We are going to create a Movie model and implement some CRUD actions for this model as well. Also, each Movie has a cast where we will have a relation to our Celebrities.

Let's jump right in.

First of all, we'll need to create the Movie model.

The Movie model should have:

• title - String
• genre - String
• plot - String
• cast - Array of Object Id's referencing the Celebrity model

So far we don't have any movies in our database so let's enable a user to add new celebrities to the database

Go ahead and create the nececessary routes and views as you did for the celebrities.

One thinng is missing at creation of a new movie. We don't add any celebrities to the cast yet. We want a select in the form of the new movie view where we can choose from all of the celebrities that are in our database and add them to the movie.

You'll need to:

• In the route that renders the view with the form to add a movie get all the celebrities from the database and pass them to the view
• In the view render a select that shows the list of the celebrities - watch out: it has to be possible to select multiple celebrities
• In the post route add the cast to the movie model at creating a new movie

Okay, the next step is to displaying a list of all movies in an index view

Here's the route we will be using:

Review how you did this for the Celebrity model.

• In the view we want to display the title, genre and plot for every movie
• We also want to show an unordered list with all the actors playing in the movie
• to have access in the view to the properties of the celebrities in the cast array you will have to populate them in the route

Final piece of our CRUD puzzle: editing existing movies.

Review how you did this for the Celebrity model - it is done exactly the same way for now.

This one is a little bit tricky. You have to pass all the celebrities to the edit view. And make sure that all the actors that are part of the cast are selected. You'll have to create a custom handlebars helper function for that.

Happy Coding! ❤️
