我创建了3个require 'json'
# Initial set up, it seems the root keys are always the same looking at your structure
products = {
'type' => 'category',
'properties' => {
'name' => 'Alcoholic Beverages'
},
'children' => []
}
data = [{
"category" => ['Alcoholic Beverages', 'Wine', 'Red Wine'],
"name" => 'Robertson Merlot',
"barcode" => '123456789-000',
"wine_farm" => 'Robertson Wineries',
"price" => 60.00
}]
data.each do |item|
# Make sure we set the current to the top-level again
curr = products['children']
# Remove first entry as it's always 'Alcoholic Beverages'
item['category'].shift
item['category'].each do |category|
# Get the index for the category if it exists
index = curr.index {|x| x['type'] == 'category' && x['properties']['name'] == category}
# If it exists then change current hash level to the child of that category
if index
curr = curr[index]['children']
# Else add it in
else
curr << {
'type' => 'category',
'properties' => {
'name' => category
},
'children' => []
}
# We can use last as we know it'll be the last index.
curr = curr.last['children']
end
end
# Delete category from the item itself
item.delete('category')
# Add the item as product type to the last level of the hash
curr << {
'type' => 'product',
'properties' => item
}
end
puts JSON.pretty_generate(products)
元素。每个表单包含8个文本字段。如果单击“提交”按钮，我在这些文本字段中输入的数据将转换为JSON格式，最后发布到我的数据库中。我正在使用AJAX后调用。我的代码是：
form请更正我的代码。我想知道如何将3个表单的数据转换为单个JSON对象。如果我的方法有误，请发布任何样本。如何实现这一目标？
