How to access AG Grid params.data element for which the key contains a space?

Dash Python
1

I am running python 3.12.4 dash 2.17.1 dash_ag_grid 31.2.0 on linux OpenSUSE Tumbleweed

I am using Dash AG Grid to build a table.

I am trying to format certain rows based on the value of the first field in the row. I am referencing params.data.fieldName as shown below, but the fieldName contains a space. How can I access the contents of params.data.fieldName if fieldName contains a space and is actually ‘Strategy Name’ (not ‘StrategyName’)?

getRowStyle = {
“styleConditions”: [
{“condition”: “params.data.StrategyName == ‘Util’”, “style”: {“backgroundColor”: “grey”},},
],
},

I have searched extensively but not found any answer. Any help is much appreciated.

Hi @gatomulato and welcome to the Dash community :slightly_smiling_face:

Good question! You can find lots of good tips in the Troubleshooting section, such as the topic of Dot Notation Not Working

You can use brackets - just like in Pandas. So instead of params.data.StrategyName you can use params.data["Strategy Name"]

Thank you for your answer.

Firstly, I apologise because I did not find the section Dot Notation Not Working. I try to not ask questions that I can answer myself, so I guess my seach-fu needs improvement.

I did try python brackets before posting. I used single quotes because the condition is already wrapped in double quote. It failed to work, but I realise now I did not remove the dot from the syntax. The following works great.

getRowStyle = {
“styleConditions”: [
{“condition”: “params.data[‘Strategy Name’] == ‘Util’”, “style”: {“backgroundColor”: “grey”},},
],
},

Thanks again.
