我有一个结果和一个发电机。生成器has_one结果。结果属于生成器。在我的协会中，我做了类似的事情：
结果表单（我在Generator SHOW.HTML）
<%= form_for([@generator,@generator.build_result(params[:result])]) do |f|%>
<script>
$(document).ready(function(){
$("#accession_number").click(function(){
$("#FASTA").hide();
$("#highlight").hide();
})
$("#FASTA").click(function(){
$("#accession_number").hide();
$("#highlight").hide();
})
$("#reset").click(function(){
$("#accession_number").show();
$("#FASTA").show();
$("#highlight").show();
})
});
</script>
<font size ="6">*** <u>Choose ONE of the input methods</u> *** </font>
<p id="accession_number">
<label><strong><font size ="3">NCBI accession number:</font></strong></label><br />
<%= f.text_field(:ncbi_ref_seq,placeholder: 'Accession Number')%>
</p>
<p id="highlight"><font size ="5">
OR
</font></p>
<p id="FASTA">
<strong><font size ="3">Paste your sequence here: ( FASTA format ) :</font></strong>
<%= f.text_area(:genome_seq,size: "50x10",placeholder: 'Input your sequence here')%>
</p>
<input type="reset" value="Reset" id="reset">
<%= f.submit 'Analyze' %>
<% end %>
结果控制器
def new
@result=Result.new
end
# POST /results :url=> generator_results_path(@generator)
# POST /results.json TGATGAACATCATGATGAGGTGATGACATCACATCATTGACTGATGCATCATGATG
def create
@generator = Generator.find(params[:generator_id])
@result = @generator.build_result(params[:result])
@generator =@result.generate_result(result_params)
@generator=@generator.save
redirect_to generators_path
end
但是，在提交表单后，我收到错误：
保存未定义
我可以知道为什么吗？我该如何解决它们呢？
