我知道有一些关于此问题的帖子，但是从我看到的内容来看，它们已经很旧了，可能已经过时了。
我正在使用 devise 和 devise_invitable。其背后的想法是允许管理员和教师邀请新用户（学生或教师）。但是当我发送邀请时，出现以下错误：
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

@virtual_path = "devise/mailer/invitation_instructions";; @output_buffer.safe_append='<p>'.freeze; @output_buffer.append=( t("devise.mailer.invitation_instructions.hello", email: @resource.email) ); @output_buffer.safe_append='</p>
<p>'.freeze; @output_buffer.append=( t("devise.mailer.invitation_instructions.someone_invited_you", url: root_url) ); @output_buffer.safe_append='</p>
<p>'.freeze; @output_buffer.append=( link_to t("devise.mailer.invitation_instructions.accept"), accept_invitation_url(@resource, invitation_token: @token) ); @output_buffer.safe_append='</p>
我尝试了很多不同的东西，现在我的代码是这样的：
邀请控制器
class Users::InvitationsController < Devise::InvitationsController
def create
super do |resource|
if resource.persisted? && resource.role == "aluno"
AlunoProfile.create(
user: resource,
morada: params[:user][:morada],
birthdate: params[:user][:birthdate],
nif: params[:user][:nif],
numero_utente: params[:user][:numero_utente],
cartao_cidadao: params[:user][:cartao_cidadao],
validity: params[:user][:validity],
contacto: params[:user][:contacto],
encarregado_educação: params[:user][:encarregado_educação],
grau_parentesco: params[:user][:grau_parentesco],
contacto_emergencia: params[:user][:contacto_emergencia],
aulas: params[:user][:aulas],
horario_preferencial: params[:user][:horario_preferencial],
recolha_dados: params[:user][:recolha_dados],
fotografias_captadas: params[:user][:fotografias_captadas]
)
end
end
end
private
def set_params
params.require(:user).permit(:email, :first_name, :last_name)
end
end
Invitation_instructions 视图
<p><%= t("devise.mailer.invitation_instructions.hello", email: @resource.email) %></p>
<p><%= t("devise.mailer.invitation_instructions.someone_invited_you", url: root_url) %></p>
<p><%= link_to t("devise.mailer.invitation_instructions.accept"), accept_invitation_url(@resource, invitation_token: @token) %></p>
<% if @resource.invitation_due_at %>
<p><%= t("devise.mailer.invitation_instructions.accept_until", due_date: l(@resource.invitation_due_at, format: :'devise.mailer.invitation_instructions.accept_until_format')) %></p>
<% end %>
<p><%= t("devise.mailer.invitation_instructions.ignore") %></p>

使用 Devise_invitable 发送邀请时出错
