    <p>I've written some code that works when typed directly into the interpreter, but fails when called. </p> <p>Here's some code (there's a lot here to make it reproducible):</p> <pre><code>import scikits.statsmodels.api as sm import pandas as pd data = sm.datasets.longley.load() df = pd.DataFrame(data.exog, columns=data.exog_name) y = data.endog df['intercept'] = 1. olsresult = sm.OLS(y, df).fit() olsresult2 = sm.OLS(y, df[['GNP', 'UNEMP', 'ARMED']]).fit() olsresult3 = sm.OLS(y, df[['GNP', 'POP', 'ARMED', 'YEAR']]).fit() models = [olsresult, olsresult2, olsresult3] class generateTable(object): def __init__(self, output, models, center='True', parens='se', var_names=None): self.output = output self.models = models self.center = center self.parens = parens self.var_names = var_names def createModel(self): results = [] for model in self.models: params = dict(model.params) bse = dict(model.bse) pvals = dict(model.pvalues) results.append(dict((k, [params[k], bse[k], pvals[k]]) for k in sorted(params.iterkeys()))) tempModel = {} for key in results[0]: tempModel[key] = [results[0][key]] for model in results[1:len(results)]: for key in model: if key not in tempModel: tempModel[key] = [['', '', '']] for i in range(1,len(results)): diff = set(tempModel) - set(results[i]) for key in results[i]: tempModel[key].append(results[i][key]) for key in diff: tempModel[key].append(['','','']) if self.var_names == None: self.inputModel = tempModel elif type(self.var_names) == list: replace = self.var_names newResults = [] resultsList = sorted(tempModel.iteritems()) for item in resultsList: newVar = list(item) newResults.append(newVar) for i in range(len(newResults)): newResults[i][0] = replace[i] self.inputModel = dict(newResults) </code></pre> <p>Whenever I try to run the script I receive an error <code>AttributeError: 'generateTable' object has no attribute 'model'</code>. IPython points out the line <code>bse = dict(model.bse)</code>. Again, this works when I run it interactively (i.e. chunk by chunk, no class), but when I import the file and try to run it I receive the error.</p> <p><strong>EDIT:</strong></p> <p>1) How is it being created?</p> <pre><code>import project a = project.generateTable('/path/to/test.tex', models, center='True', parens='se', var_names=None) a.createModel() </code></pre> <p>2) The whole traceback is: </p> <pre><code>In [26]: a.createModel() --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /path/to/project/&lt;ipython-input-26-6774b6d1804c&gt; in &lt;module&gt;() ----&gt; 1 a.createModel() /path/to/project/project.py in createModel(self) 39 for model in models: 40 params = dict(model.params) ---&gt; 41 bse = dict(model.bse) 42 pvals = dict(model.pvalues) 43 results.append(dict((k, [params[k], bse[k], pvals[k]]) for k in sorted(params.iterkeys()))) </code></pre> <p>3) I'm going to try changing the var name <code>model</code> to something else. </p> <p>4) Sorry about the syntax error. Thank you, asmeurer, for the fix.</p> <p><strong>EDIT 2:</strong></p> <p>3 above (changing the var name <code>model</code> to something else) didn't work. </p> <h2>EDIT 3:</h2> <p>It works now. Here's the latest code:</p> <pre><code>def __init__(self, output, models, center='True', parens='se', var_names=None): self.output = output self.models = models self.center = center self.parens = parens self.var_names = var_names def createModel(self): results = [] for test_model in self.models: params = dict(test_model.params) bse = dict(test_model.bse) pvals = dict(test_model.pvalues) results.append(dict((k, [params[k], bse.get(k), pvals.get(k)]) for k in sorted(params.iterkeys()))) </code></pre> <p>The only thing that's different is model in the for loop has been changed to test_model. I tried that before and it didn't work, so I'm not quite sure how it happend. </p> <p>Thanks everyone for the help! And if anyone could point how why this change got rid of that particular error message it'd be greatly appreciated. I'd like to actually know what I was doing instead of just moving on and accepting it. </p>

    1. COCould you show how you are creating the generateTable objects / calling the createModel methods?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
