这将是一个很难提供意见的问题，所以我会尽可能详细地提供。以下是我试图弄清楚的确切问题。出于某种原因，当我保存时，经验是删除列中的所有其他值并在更新当天写入。我刚刚保存了所有其他值，但为了清楚起见，我将它们排除在表之外。最奇怪的部分是预算和经验设置完全相同，但不幸的是并没有节省相同的费用。下面是关于这个问题的更多细节。
非常感谢您对可能发生的事情的任何见解。

这些是表单（视图）的输入
<div class="row clearfix">
<div class="label">Budget</div>
<div class="mid budget">
<div class="mid">
<input class="venProfileInputs caps" name="bar_profile[<%= day %>][budget]" onblur=checkBudVals(this)>
</div>
</div>
</div>
<div class="row clearfix">
<div class="label">Experience</div>
<div class=" mid">
<input class="venProfileInputs caps" name="bar_profile[<%= day %>][experience]" onblur=checkExVals(this) />
</div>
</div>
然后进入控制器
def update
@bar = Bar.find(params[:id])
if @bar.update_attributes(params[:bar])
@bar.update_profiles(params[:bar_profile])
redirect_to "/admin", :notice => "Bar was successfully updated."
else
render :action => :edit
end
end
它在模型中得到更新
def update_profiles(params)
profiles.each {|p| p.destroy }
params[:active_profiles].split(',').each do |profile_day|
next if profile_day.blank?
add_profile(params[profile_day.to_sym])
# sets up crowd tags
crowd_tags_ids = params[profile_day.to_sym][:tags]
unless crowd_tags_ids.blank?
crowd_tags_ids.split(',').each do |tag_id|
next if tag_id.strip == ""
profiles.last.crowd_tags << CrowdTag.find(tag_id)
end
end
profiles.last.set_crowd_tags
#need to loop through cf_tags_ids = params[profile_day.to_sym][:cf_tags]
cf_tags_ids = params[profile_day.to_sym][:cf_tags]
unless cf_tags_ids.blank?
# loop through each category 0,1,2,3,4
cf_tags_ids.each_pair{ |cat, ids|
#cycle through each id in the current cat and add to crowd fiter tag
ids.split(',').each do |cf_id|
next if cf_id.strip == ""
profiles.last.crowd_filter_tags << CrowdFilterTag.find(cf_id)
end
}
end
profiles.last.set_cf_tags
# below is not working for saving experience
profiles.last.experience = params[profile_day.to_sym][:experience]
logger.info "#{profiles.last.inspect}"
#### Still need to save experience some how, budget seems to be getting saved
# but only one value for experience is being logged in a single row for each bar_id
end
end
