1st part –
(get user’s email, send message with url-code to that email)
– all ok

2nd part –
(user go to url-code and set up new password for him account)
— is not ok

(phoenix 1.2.1, Elixir 1.3.1)

in router

get “/remind-password/:email/:remind_code”, PageController, :setup_remind_password
post “/remind-password/:email/:remind_code”, PageController, :do_setup_remind_password

in Controller

def setup_remind_password(conn, %{“email” => email, “remind_code” => remind_code}) do
changeset = Planetwork.EmailRemindPasswordCode.changeset
render conn, “setup_remind_password.html”, changeset: changeset, email: email, remind_code: remind_code
end

def do_setup_remind_password(conn, params) do
case Planetwork.EmailRemindPasswordCode.changeset(%Planetwork.EmailRemindPasswordCode{}, params)
do
{:ok, changeset} →
conn
|> put_session(:user_id, changeset.changes.account_id)
|> redirect(to: “/cabinet”)
{:error, changeset} →
render conn, “setup_remind_password.html”, changeset: changeset, email: params[“email”], remind_code: params[“remind_code”]
end
end

in template

<%= form_for @changeset, page_path(@conn, :do_setup_remind_password), [id: "remind-password-form", class: ""], fn f -> %> 
<div class="row">
  <div class="input-field col s12">
    <label for="remind_password_form_password"><%= gettext "Password" %></label>
    <%= password_input f, :password, required: true, class: validate(f, :password), id: "remind_password_form_password" %>
    <%= error_tag f, :password %>
  </div>
</div>

<div class="center">
  <button class="center btn waves-effect" type="submit"><%= gettext "Save password" %></button>
</div>

<% end %>

Why phoenix says that i have error in template at string

<%= form_for @changeset, page_path(@conn, :do_setup_remind_password), [id: “remind-password-form”, class: “”], fn f → %>
???

Should be
page_path(@conn, :do_setup_remind_password, [id: “remind-password-form”, class: “”])

Please try. If it works.
Also check the documentation, that the last arg in the function should be a map instead of a list. I don’t remember. I will check up the docs and update here again.

[Edit] I checked out from doc. The last parameter of the path is a keyword list. So putting the last optional args as a list is right. Sorry for bothering putting this point up.

Ok. So now I try your code in computer and look up for the docs. Sorry for the delay.

The following code path is wrong -

page_path(@conn, :do_setup_remind_password), [id: “remind-password-form”, class: “”]

Since

post “/remind-password/:email/:remind_code”, PageController, :do_setup_remind_password

page_path/4 (arity 4) for u.

So to make it pass - you have to put email, and remindcode as the third and fourth parameter here. - So for sample to make it work please see below code and try to adapt from it. I will put everything in the link helper below.

link(“Some text here”, to: page_path(@conn, :do_setup_remind_password, “email here”, "remind-code-herge))

and if you want to put classes and Id also you can put it as a keyword list at the third parameter of the link function.

link(“Some text here”, to: page_path(@conn, :do_setup_remind_password, “email here”, "remind-code-herge), [class: “classa classb”, id: “Myid”])

Sorry for the delay.
I hope you understand.

Those error messages are confusing so I have pushed changes to Phoenix master that make sure everything is a bit more explicit. Now the error should suggest you to use:

page_path(conn_or_endpoint, :do_setup_remind_password, email, remind_code, opts \\ [])

which is basically what @blisscs suggested.
