+Hi everyone
+
+**Problem with some code highlighting for this part of the series. An issue has been opened.**
+
+Welcome to part 7 of the series but before we jump in let's recap what we did in the sixth part:
+
+- homework: Create a Context `Accounts` with a `User` Schema and a `Users` Migration with `username` field and `password` field.
+
+- Bonus: Create a `User` query and a `User` type.
+
+**How was this exercise for you *Dear Reader* did you managed to build it?**
+
+**Section navigation**
+
+- [User context with schema and migration](#section-1)
+
+- [User query and user type](#section-2)
+
+So we will have two sections today in the first part we are going to create a Context `Accounts` with a `User` Schema and a `Users` Migration with `username` field and `password` field.
+
+In the second part, we are going to create a `User` query and a `User` type.
+
+#Section 1
+User context with schema and migration
+
+Let's create a new branch using:
+
+```shell
+hub checkout -b 01-User 
+```
+
+```shell
+mix phx.gen.context Accounts User users username:unique password
+mix ecto.migrate
+```
+
+With these commands we finished the first part of our homework and can add our work to git
+
+```shell
+hub add .
+
+hub commit -m "User context with schema and migration"
+
+hub push --set-upstream origin 01-User
+```
+
+#Section 2
+User query and user type
+
+Create a new file in: `lib/wolf_blog_web/types` and call it `user_types.ex`
+
+```elixir
+defmodule WolfBlogWeb.Types.UserTypes do
+  use Absinthe.Schema.Notation
+
+  @desc "User fields that can be interrogated(get)"
+  object :user do
+    @desc "The user id"
+    field :id, :id
+    @desc "The username of the user"
+    field :username, :string
+    @desc "The password of the user"
+    field :password, :string
+  end
+end
+```
+
+Now change `schema.ex` to this:
+
+```elixir
+defmodule WolfBlogWeb.Schema do
+  use Absinthe.Schema
+  alias WolfBlogWeb.Resolvers.PostResolver
+
+  import_types(WolfBlogWeb.Types.PostTypes)
+  import_types(WolfBlogWeb.Types.UserTypes)
+
+  query do
+    @desc "list_all_posts"
+    field :posts, list_of(:post) do
+      resolve(&PostResolver.list_all_posts/3)
+    end
+
+    @desc "list_all_users"
+    field :users, list_of(:user) do
+      resolve(&UserResolver.list_all_users/3)
+    end
+  end
+end
+```
+
+The new part that we added to the  `schema.ex` is this:
+
+```elixir
+@desc "list_all_users"
+ field :users, list_of(:user) do
+ resolve(&UserResolver.list_all_users/3)
+ end
+```
+
+This completes the bonus section of the homework **Dear Reader**.
+
+
+
+But wait, Wolfiton I get an error that my resolver is not found?!
+
+
+
+I am glad you noticed **Dear Reader**
+
+
+
+As you can remember from our previous articles in these series. To make `Phoenix` and `Absinthe` work together we need a `Resolver` to connect the `Context` with our `Schema`.
+
+
+
+So in `lib/wolf_blog_web/resolvers`, create a new file called `user_resolver.ex`
+
+```elixir
+defmodule WolfBlogWeb.Resolvers.UserResolver do
+  alias WolfBlog.Accounts
+
+  def list_all_users(_, _, _) do
+    {:ok, Accounts.list_users()}
+  end
+end
+```
+
+So now we only need to add this alias in `schema.ex`:
+
+`alias WolfBlogWeb.Resolvers.UserResolver`
+
+So our `schema.ex` will look like this:
+
+
+```elixir
+defmodule WolfBlogWeb.Schema do
+  use Absinthe.Schema
+  alias WolfBlogWeb.Resolvers.PostResolver
+  alias WolfBlogWeb.Resolvers.UserResolver
+
+  import_types(WolfBlogWeb.Types.PostTypes)
+  import_types(WolfBlogWeb.Types.UserTypes)
+
+  query do
+    @desc "list_all_posts"
+    field :posts, list_of(:post) do
+      resolve(&PostResolver.list_all_posts/3)
+    end
+
+    @desc "list_all_users"
+    field :users, list_of(:user) do
+      resolve(&UserResolver.list_all_users/3)
+    end
+  end
+end
+```
+
+Now let's add all our modifications to GitHub:
+
+```shell
+hub add .
+
+hub commit -m "Added User query with user types and a user resolver"
+
+hub push
+```
+
+
+
+Part 7 is finished, I hope you enjoyed **Dear Reader**.
