Django Json在DB中保存了如何在模板中使用？

Question

我想在DB中保存Json数据，然后在模板中显示它。

数据保存为：

{"reaction": [{"reactionmeddrapt": "Stress fracture", "reactionmeddraversionpt": "20.1", "reactionoutcome": "1"}, {"reactionmeddrapt": "Drug effect incomplete", "reactionmeddraversionpt": "20.1", "reactionoutcome": "6"}, {"reactionmeddrapt": "Osteoarthritis", "reactionmeddraversionpt": "20.1", "reactionoutcome": "3"}, {"reactionmeddrapt": "Fracture delayed union", "reactionmeddraversionpt": "20.1", "reactionoutcome": "6"}, {"reactionmeddrapt": "Knee arthroplasty", "reactionmeddraversionpt": "20.1", "reactionoutcome": "6"}], "drug": [{"medicinalproduct": "PROLIA", "drugindication": "PRODUCT USED FOR UNKNOWN INDICATION", "drugadministrationroute": "065", "drugdosagetext": "UNK, Q6MO", "openfda": {"manufacturer_name": ["Amgen Inc"], "unii": ["4EQZ6YO2HI"], "product_type": ["HUMAN PRESCRIPTION DRUG"], "rxcui": ["993452", "993456"], "spl_set_id": ["49e5afe9-a0c7-40c4-af9f-f287a80c5c88"], "route": ["SUBCUTANEOUS"], "generic_name": ["DENOSUMAB"], "brand_name": ["PROLIA"], "product_ndc": ["55513-710"], "pharm_class_epc": ["RANK Ligand Inhibitor [EPC]"], "substance_name": ["DENOSUMAB"], "spl_id": ["f0a4aa32-b689-4a2a-b575-7b3156e79c0c"], "pharm_class_moa": ["RANK Ligand Blocking Activity [MoA]"], "application_number": ["BLA125320"], "nui": ["N0000187054", "N0000187055"], "package_ndc": ["55513-710-01"]}, "drugdosageform": "SOLUTION FOR INJECTION", "drugcharacterization": "1", "activesubstance": {"activesubstancename": "DENOSUMAB"}, "drugauthorizationnumb": "125320", "actiondrug": "5", "drugadditional": "3"}]}

在我看来，我使用json.loads(json_data)转换了这些数据

现在我试图在模板中迭代它但不能这样做。

我已经尝试使用json_data和json.loads而没有json.loads。 它似乎不起作用。

我已经尝试了模板中的所有内容{% for key, value......并直接{{json_data.field_name}}

这似乎是关于SO的最常见问题之一，到目前为止还没有具体答案。

如果字典的格式是固定的，为什么不分别循环药物和反应并手动打印模板中的东西？

您可以根据需要编辑HTML。 如果其中一些项目是列表，您也可以循环遍历它们。 例如，我在以下代码片段中循环遍历drug.openfda.rxcui 。

{% for drug in json_data.drug %}
    <p>Actiondrug: {{ drug.actiondrug }}</p>
    <p>Activesubstance: {{ drug.activesubstance.activesubstancename }}</p>
    <p>Drugadditional: {{ drug.drugadditional }}</p>
    <p>Drugadministrationroute: {{ drug.drugadministrationroute }}</p>
    <p>Drugauthorizationnumb: {{ drug.drugauthorizationnumb }}</p>
    <p>Drugcharacterization: {{ drug.drugcharacterization }}</p>
    <p>Drugdosageform: {{ drug.drugdosageform }}</p>
    <p>Drugdosagetext: {{ drug.drugdosagetext }}</p>
    <p>Drugindication: {{ drug.drugindication }}</p>
    <p>Medicinalproduct: {{ drug.medicinalproduct }}</p>

    <p>OpenFDA</p>

    <p>application_number: {{ drug.openfda.application_number }}</p>
    <p>brand_name: {{ drug.openfda.brand_name }}</p>
    <p>generic_name: {{ drug.openfda.generic_name }}</p>
    <p>manufacturer_name: {{ drug.openfda.manufacturer_name }}</p>
    <p>nui: {{ drug.openfda.nui }}</p>
    <p>package_ndc: {{ drug.openfda.package_ndc }}</p>
    <p>pharm_class_epc: {{ drug.openfda.pharm_class_epc }}</p>
    <p>pharm_class_moa: {{ drug.openfda.pharm_class_moa }}</p>
    <p>product_ndc: {{ drug.openfda.product_ndc }}</p>
    <p>product_type: {{ drug.openfda.product_type }}</p>
    <p>route: {{ drug.openfda.route }}</p>

    {# example of looping through a list #}
    <p>rxcui: {% for r in drug.openfda.rxcui  %}{{ r }}{% endfor %}</p>

    <p>spl_id: {{ drug.openfda.spl_id }}</p>
    <p>spl_set_id: {{ drug.openfda.spl_set_id }}</p>
    <p>substance_name: {{ drug.openfda.substance_name }}</p>
    <p>unii: {{ drug.openfda.unii }}</p>

{% endfor %}

{% for reaction in json_data.reaction %}
    {% for key, val in reaction.items %}
        <p>reactionmeddrapt: {{ reaction.reactionmeddrapt }}</p>
        <p>reactionmeddraversionpt: {{ reaction.reactionmeddraversionpt }}</p>
        <p>reactionoutcome: {{ reaction.reactionoutcome }}</p>
    {% endfor %}
{% endfor %}
