Question

我试图为分销商数据插入新分支以传递给Sinatra。它能够插入新记录，但会产生此错误：

"ERROR Rack::Lint::LintError: body yielded non string value [:disBranchID, 27]"

disBranchID是表格的主键，并设置为自动递增。

HTML看起来像这样：

<form name="add_dis_branch_form" action="/add_dis_branch" method="post" id="disB" enctype="multipart/form-data">
    <div class="input-group">
        <span class="input-group-addon"> Brand </span>
        <select id="disSlcMan" class="btn btn-default full-width" name="disID" ng-model="disB.disID" required>
            <option value="">Select Brand</option>
            <% AutoMobile::DB[:distributor].select(:disID, :disComName).each do |dis| %>
                <option value="<%= dis[:disID]%>"><%= dis[:disComName] %></option>

Sinatra代码：

add_dis_branch = lambda do

    newBranch = AutoMobile::DisBranch.new

    newBranch.address   = params[:address]
    newBranch.city      = params[:city]
    newBranch.state     = params[:state]
    newBranch.zip       = params[:zip]
    newBranch.phone     = params[:phoneNo]
    newBranch.fax       = params[:faxNo]
    newBranch.latitude  = params[:latitude]
    newBranch.longitude = params[:longitude]
    newBranch.disID     = params[:disID]

    newBranch.save
end

Answer 1

以下是编写路线的一种方法：

post "/automobile/branch" do
  newBranch = AutoMobile::DisBranch.new

  newBranch.address   = params[:address]
  newBranch.city      = params[:city]
  newBranch.state     = params[:state]
  newBranch.zip       = params[:zip]
  newBranch.phone     = params[:phoneNo]
  newBranch.fax       = params[:faxNo]
  newBranch.latitude  = params[:latitude]
  newBranch.longitude = params[:longitude]
  newBranch.disID     = params[:disID]

  newBranch.save

  halt 201
end

但我建议您仔细阅读Sinatra on creating routes和Sequel on creating model instances的文档。

sinatra身体产生非弦值
