Rails Error

SQLite3 table xxx already exists

修改 20160213082813_create_variants.rb 在create_table前一行加入

drop_table :variants

syntax error, unexpected ')', expecting keyword_end ...lass="form-control input-sm") );@output_buffer.safe_append=' ... ^

出错代码：

<%= text_field_tag(:q,params[:q], placeholder: "商品名称", class="form-control input-sm") %>

应该改为：

class: "form-control input-sm"

uninitialized constant ProfileController
