html - Django : Could not parse the remainder: '{{' from '{{

Question

当我执行HTML代码时，会出现以下错误:

Could not parse the remainder: '{{' from '{{'

我也尝试嵌套条件，但是我绝对是HTML的初学者，所以我希望至少获得正确的版本，但是它不起作用...

{% block content %}
<p align="justify"> So far you donated {{ donated_trees }} Tree(s).  </p>
 {% if treatmentgroup == 'two' or treatmentgroup == 'three' %}
    Your current position is {{ player.end_position }} of {{ anzahlspieler }} for the most donated trees.
{% endif %}

 {% if treatmentgroup == 'two' or treatmentgroup == 'three' and {{ player.rival }} == 0 %}
<P>     No other player has the same.</P>
{% endif %}

 {% if treatmentgroup == 'two' or treatmentgroup == 'three' and {{ player.rival }} == 1 %}
<P>     One other player has the same.</P>
{% endif %}

{% if treatmentgroup == 'two' or treatmentgroup == 'three' and {{ player.rival }} > 1 %}
<P>     {{ player.rival }} other players have the same.</P>
{% endif %}

从第8行开始发生错误。

您不能在模板标记内使用{{ … }}，而只能使用变量本身:

{% block content %}
<p align="justify"> So far you donated {{ donated_trees }} Tree(s).  </p>
 {% if treatmentgroup == 'two' or treatmentgroup == 'three' %}
    Your current position is {{ player.end_position }} of {{ anzahlspieler }} for the most donated trees.
{% endif %}

 {% if treatmentgroup == 'two' or treatmentgroup == 'three' and player.rival == 0 %}
<P>     No other player has the same.</P>
{% endif %}

 {% if treatmentgroup == 'two' or treatmentgroup == 'three' and player.rival == 1 %}
<P>     One other player has the same.</P>
{% endif %}

{% if treatmentgroup == 'two' or treatmentgroup == 'three' and player.rival > 1 %}
<P>     {{ player.rival }} other players have the same.</P>
{% endif %}
