我想你可以通过添加一个隐藏的输入字段来实现你想要的item_id
例子:
< td>
< div class =form-group>
< input type =numberid =amountname =amountvalue ={{i.order_quantity}}>
< input type =hiddenname =item_idvalue ={{i.item_id}}/>
< / div>
< / td>
当您在Flask中接收到输入时,您可以将ID与自订单保留以来的金额。
$ b $ pre $ amount = request.form.getlist('amount')
/ pre>
item_ids = request.form.getlist(' item_id')
for item_id,idx in enumerate(item_id):
amount = amount [idx]
#使用item_id和金额
I have a dynamically generated number of rows containing text boxes in a table with a default value (order_quantity). Basically on a post I want my items table in sql to be updated with the values of these text boxes according to their ID's.
{% for i in items %}
<tr>
<td>
...
</td>
<td>
...
</td>
<td>
<div class="form-group">
<input type="number" id="amount" name="amount" value="{{ i.order_quantity }}">
</div>
</td>
<td>
...
</td>
</tr>
{% endfor %}
There's no problem passing in the order_quantity OR the item ID but not both obviously.
HTML:
<input type="number" id="amount" name="amount" value="{{i.item_id}} {{ i.order_quantity }}">
Python:
amount = request.form.getlist('amount')
print amount
for i in amount:
print i
In summary, how can I pass both the quantity and its relative id out in a simplistic manner for easy server-side extraction for each text box?
I think you can achieve what you want by adding a hidden input field that holds the item_id
Example:
<td>
<div class="form-group">
<input type="number" id="amount" name="amount" value="{{ i.order_quantity }}">
<input type="hidden" name="item_id" value="{{ i.item_id }}"/>
</div>
</td>
When you receive the input in Flask, you can match the id's to the amounts since the order is preserved.
amounts = request.form.getlist('amount')
item_ids = request.form.getlist('item_id')
for item_id, idx in enumerate(item_id):
amount = amounts[idx]
# do something with item_id and amount
