Peewee - 以 10 为底的 int() 的无效文字：'' 在循环查询时
Peewee - invalid literal for int() with base 10: '' when looping over query
我正在尝试遍历 Peewee 查询对象，当我尝试访问循环查询的模板时出现以下错误：
ValueError: invalid literal for int() with base 10: ''
您将在下面看到视图函数和模板的完整回溯和代码。我什至尝试将模板循环简化为：
{% for company in companies %}
<p>{{ company.company_name }}</p>
{% endfor %}
我仍然遇到同样的错误。

您的模型似乎声明了 IntegerField，但数据库中存储了一个空字符串。也许你可以去清理你的数据库：
UPDATE whatever SET int_field = NULL WHERE int_field = '';
